The apartment was neat, spacious, nice and clean - it had everything and more. Great kitchen for making a breakfast. I have absolutely no complaints there.
But - there was absolutely no mention that the whole building next door (right next to the dormitories) is being renovated. We had vacations and came home very late from the center each day - tired, but there was no way in hell we could sleep after 8:00 am. One day they were also changing the front door of the apartment building. That made the noise even worse - nobody warned us about that either.
I feel like there could be a note somewhere, that the Charles Bridge is a 30 minutes walk from the apartment - since this is one of the first things people want to see. If you want to explore the castle and old town by foot, be ready to walk 30 min one way. There is a metro 5 min away, so if you don't mind taking it, then you should be fine.
