We really enjoyed the location and the hotel bar/restaurant. Staff in the bar were absolutely amazing. On 3 of our 4 nights, we went down for happy hour and twice got dinner. Best steaks we had on our whole trip, US or CA. The two lads should come to Ireland on holidays, sure they'd love it.

First night, some people in the room down the hall had a party from 2.30am to 5.30am with sane crappy song on repeat. Couldn't phone lobby as phone wasn't charged ended up using my mobile phone. Room was very dry at night but these complaints wouldn't stop me returning to 21c

I didn’t have much time but checking in was very easy. The front desk was very friendly and communicative. Everything was clean and exciting to view.

Checking out was a hassle. A lot of people crowded toward the front desk and a man with a clipboard just choosing who to ask if they need help. In no particular order. I stood in line for maybe 15 minutes before I finally flagged the man down and said “I just need to check out”. I wish that process was smoother.

The property is in great condition. The rooms are clean.

I was charged almost $500 for a one night reservation that was supposed to be $180. I was told it by Jose it would be taken care of. It was not. I called and spoke to a supervisor who said she would get back to me. She did not. I called the next day and spoke with Jose - he said he would “pass along my message” to the supervisor. I have yet to hear back from anyone.

Perfect for a few days for a couple. Amazing , spacious and modern room, without any noise from the city so we could sleep well. The shower was really good Super comfortable bed

When we arrived the receptionist was very rude and arrogant

Lobby

Overpriced, overcrowded, bad elevators and overcrowded. They gave me a disability room. Bathroom light flashing. Some guests screaming at aisle. My door was knocked by one of them at 2:30 am.

The staff was somewhat helpful--the engineer was especially friendly.

Prior to my stay, the 21C was one of my favorite hotel chains. After my stay, I have no desire to ever stay at one of their properties again. Here a few of the things that went wrong: - The hotel did not offer room service, nor did it have plates and eating utensils - The hotel did not deliver food from the onsite hotel - The TVs were old and did not offer streaming - Our original hotel room had water damage on the ceiling and coffee table, and the door separating the bedroom and the living room didn't work - The front desk staff was not terribly friendly and tried to cut me off when I told them about my frustrations with the property - The room was very noisy because of the sounds from the street - The linens weren't uniform - The hallways were dark and the walls looked like they had an abandoned paint job

Perfect location within the city, and a lovely building with nice rooms and beautiful art exhibits and friendly staff.

Not much. The restaurant randomly closed early the one night we chose to come down and get drinks on our first night there before our anniversary, but they were polite and things like this happen from time to time.

The beds were nice and the furniture in the room was nice. The concept of the hotel is cool with the art gallery. Was in a pretty great location.

There were so many things that were red flags when we walked in. To start the staff could not find our reservation and it took about 30 minutes for someone to find our reservation, then for them to hold our luggage it was going to cost extra. They couldn't find us a room because they were going through a shift change, so we decided to leave. When we came back an hour later, they couldn't find our reservation again. When they finally found our reservation, we went up to our room which was quite underwhelming. The outlets were coming out of the walls, the pain was not done well, but for the most part the furniture, bed, and the bathroom looked great. It looked like they did not do much work on the actual structure to the hotel, but they put effort into the decoration. The hallways are really dark, and they covered up the service areas with only a curtain. Some things were definitely off about this hotel.
