Good place to stay, walkable distance to the Adriatic sea

Personally, I can't believe this property can rent rooms that are incredibly small, as a "four start" hotel. Not only were the rooms small, but the quality of the bed and mattress were simply horrible. If I could submit the photos here, I would. The bathroom was so small, I a 6ft, 190 Lbs, person had a hard time using the toilet. To make matters worse, when I booked the room, Orbitz showed the same price for one and two person. I booked for one, and then I went to the hotel to add one person to the room, the concierge told me I had to pay basically again a full rate for another person, which I have never heard. I showed him the screenshots with the prices that orbitz, displayed when I booked the room, and he just basically ignored me, and told me, that those were the prices. Rude concierge and dismissive of any questions I had thereafter. I have traveled around the world, and have never encountered such cold approach and treatment to a customer, nor have I encountered a pseudo 4 star hotel, with such poor quality rooms.
