I stayed in this apartment for 5 weeks and it was amazing. I was in school 12h a day and when I got "home" I would get all the peace I needed. The flat is not on the main road but a minute away so trams, shops and restaurants are close but there's not a lot of noise. Vysehrad, which is my absolute favorite part of Prague is a 10min walk away and with trams the center is 15min tops too.
The apartment is spacious and when my friends visited we had plenty of room to sleep and move around. Kitchen is well equipped, the bathroom has everything and there's a lovely garden in front of the flat.
The hosts were lovely and friendly and helped me figure out where everything was in the street and I really felt at home in their flat.
Overall, a wonderful stay.
