This is probably the only hotel in the world that I will not visit again. The photos on the webside was not true at all, nor the information. The room was the very smallest I've ever seen. The walls in the hotel must be made from paper, because I woke up several times during the night, thinking that the persons in the next room, had got into mine. There was a dog wiping and scratching on the door, he seemed to be in my room, too. There were just a very few people in the hotel, but they seemed to make a great deal of noise. I don't think they did, but I could hear every little move they made, and every word they said. Not to mention, the noise from outside. I don't think I slept more than a couple of hours each night, because of the noise.
The information said that the hotel has a staff with international languages. Well, only one of the staff were able to speak English understandable. The others didn't even know "yes" or "no". Thogh they were able to excuse their lack of language.
So - if you want to have a nice stay in Denia, don't go to the Hotel Costa Blanca. You'll be disappointed.
