Pavel was a really nice host, available and cheerful! We had to give a few information and pay a deposit in cash, which was returned without any trouble at the end of our trip. The apartment fits the description, it is sunny, comfortable, and clean. There is indeed a club right under the windows but it did not bother us, but it might disturb you if you are looking for a calm place. It was also extremely well located and from there we could visit the whole city without using the subway at all.
We enjoyed our stay in Prague!
