They allowed early checkin and we waited at the pool while our room was being prepped. This was huge as we arrived in the morning. They also held our luggage when we needed it.

Across from beach very convenient and comfortable

The room was amazing as it was the best room in the hotel. However, it was in a very noisy part of Athens and it was during a heatwave. It might have been better another time of year. The pool was quite small too.

Great location!

Everything was wonderful except the parking.

It's location and views were excellent.

Pros: + Good location, 5 minutes and you are near the beach. + Good wifi Cons: - Balcony. Not all rooms have sea views. Our room has a 1 square meter balcony. I didn't expect that - Sound isolation is terrible. You will hear everything in the nearest rooms, especially cleaning from early morning. - Staff will ignore "Do not disturb". They will call you, and knock on the door each day even after you ask not to do so. - Staff will argue if you order food delivery. They told me about some "terms and conditions" of this hotel. I asked to share the link or written text but they didn't have it. The argument is that they have a restaurant upstairs and we should order food there. The restaurant is decent and overpriced. - The air conditioner works strangely. By having the same temperature you can wake up because it's too hot or too cold. - Mini-refrigirator worked poorly. The cheese inside melts in one night. - Safe didn't work but it's minor. The beach with sun loungers and umbrellas across the street from the hotel is not included in the hotel price but has a 50% discount for people from the hotel. (7.5 euros per person with discount) In general, this hotel has the quality of 2-star hotels and the price of 5-star hotels. The biggest issue is that the staff doesn't care about you and doing it how they want to but to be completely fair they are polite.

Nice hotel close to the beach. Room was a little small for 3 people. Breakfast was amazing!

The hotel is in a great location. The staff is friendly and I love that there is a beach and pool. Housekeeping is incredible with the way they clean the rooms. Breakfast was delish.

Amazing hotel. Beautiful pool and right in front of an amazing beach with discounted lounge chairs. Best part was the staff, they were so nice.

Hotel room was very nice, two complaints would be the room AC wasn’t the greatest and the food at the hotel restaurant wasn’t very good

Good hotel with nice rooftop pool overlooking the sea

I tried to get early check-in, but not available. Totally understand, but they promised to text me when the room was ready and never did. Tried to sleep at the rooftop pool until 3pm (official check-in time), went down a few minutes after and looked like they had several rooms ready. Totally exhausted and this just pissed me off even more. Roof top pool was ok, been at much nicer. I would only stay again b/c near the beach.

Very friendly. Out of town. Nice staff. All very straight forward booking in and out.

We couldn’t have been more pleased! The rooms were awesome, the staff we incredible and the view from our room was breathtaking!

Property is right by the ocean and offers excellent views of Greece. There is a very pleasant swimming pool.

The view from the front rooms is breathtaking, but comes at the price of 24-hour noise due to a large street in front of the hotel. Also, the hotel does not allow food delivery to the rooms, but at the same time has no room service menu.

Fab location, plenty of beach bars and restaurants close by and easy to get too as there is a tram stop directly opposite the hotel. Supermarket next door, which was very convenient. I think the photos on Expedia might be slightly out dated as I thought the hotel felt more premium and better than It looks ! Which was a pleasant surprise. Girls at reception were great too, very informative and strong English. One downside is the food is massively over priced and so are the drinks. I think re looking prices would be beneficial for business and boost restaurant and pool side bar atmosphere, which was dire. I ate there once out of 6 nights as better value restaurants and bars very close by. All in all, very good. Thanks

Everything was very clean and all staff was couriteous and polite and very helpful.

Very friendly service. Great views!

Very friendly staff. Good location

Clean property. Convenient

VERY GOOD

The hotel staff is very helpful and very nice and polite. The food and drinks are amazing and the room is very cozy and clean. Loved staying here.

Property is right at a terminal for the tram into the city centre. Also, one of the stops for the "hop on hop off" bus tour is directly out front. Grocery stores and pharmacies in easy walking distance. Cross the street and you are on the beach. Some fantastic restaurants within 15 minute walking distance. We had a rental car. The hotel has limited 3-4 spots directly in front, otherwise they also have parking across the street for the beach bar. Hotel staff will also assist with parking your car. Spots were pretty limited even in the off season so don't count on easy parking , but you can get lucky on the side streets. Two small criticisms.... We used the in house laundry service and they lost one item of my wife's clothing. The other one... Early this morning of March 31 we had set an alarm for 0300 to leave plenty of time to drive the rental car back to the airport, arrive early, check in for our flight etc. My alarm went off at 0300 as planned. A few minutes later I checked the time on my phone and it was 0415.... The change from daylight savings time to standard time had occurred right at 0300 when my alarm went off. We magically lost an hour of our morning for getting to the airport. We had talked to front desk staff earlier that evening and they didn't mention time change. There was also no sign regarding time change posted for information. Overall, great experience. I'm sure the rate we received was lower because we were there at the tail end of low (winter) season.

Difficulty parking the car

I normally don't write these reviews but Poseidon exceeded all my expectations. The hotel is perfectly situated and has good transportation right outside their door. The hotel staff is very service minded and friendly. Their restaurant is top of the class and the view is amazing.

Breakfast was great. Room was great. Staff was great

The Hotel was average. Staff were friendly but overall just another hotel. Nothing stood out as being exceptional. There were no perks with VIP awards. The breakfast was well presented with good choice, but the beachfront restaurant had unfriendly staff just doing their job. The Hotel was close to tram and bus lines to and from Athens, airport and Port which was great for getting around. The one thing I will rave about is a near by restaurant called Tzitziras and Mitziras. Fantastic service and food about a 10 minute walk from the Poseidon

In general the stay was good. There was a bit of a drain smell in the bathroom so we asked to be moved. They were apologetic and gave us a room directly above the previous room. However, there was still a slight smell of drains, but not too bad! The rooms were clean with nice toiletries.Breakfast was excellent, staff were polite and welcoming.

Very nice hotel with amazing staff close to the beach, highway, and tram.

Excellent breakfast can not say enough thank you
