The apartment is very nice and in good location. You can just make a walk to the most of Prague's important places. We are quite used to city noises, so the sound of trams and other city sounds didn't bother us. Especially as there weren't any high volume parties or sth like that.
It's on the fourth floor, but there is an elevator. However it's not for disabled people, as there are few stairs to the elevator, and then there are few more to the flat.
The apartment is perfect for a few days visit, to sightsee the city. As we were dining in the city we almost didn't use the kitchen, but the fridge works ok 😊
