First of all, let's say, that David place is recommendable, especially for young people travelling together. The place locates in a neighbourhood of heavy nightlife (until cca 1-2 AM) and though the street is quiet, once you open your window, it can be noisy for some people, who are easily to be disturbed by noises.
The place has four rooms, all of them are quite small, and when all beds are in use and are open, there is no much more space left... So I'd say, the place is okay for 3-4 people tops. The bathroom is also very small. The apartment was equipped with everything promissed. That was quite convenient, also there is a store close to it, where you can buy food.
The place could be cleaner, especially the bathroom and kitchen. and also, the walls are not as white as in the advertisement. We had no chance to meet David, but his friend helped us, though we had to wait for her a little bit.
All in all, as I was saying, I would highly reccomend this place for young couples, group of friends.
