Peter's apartment is just great, very clean and nicely furnished in modern style, just as the pictures show it. Everything was there to run our own household during our stay.
The location is about 20 min. (one way) walking time from the beautiful sightseeing places in downtown, bus or tram stations are also just around the corner.
Of course there were cars driving by in front of the building (you are in a big city, but not at a main road), but with the windows closed on the street side and a big window slided open on the opposite side facing into a nice and quiet courtyard it was anyway a quiet living in this apartment.
A small grocery store is just around the corner and a big Super Market (Billa) is about 5 min. walking distance from the apartment.
Summary: a great apartment in a close-by location to the Prague sightseeing highlights, absolutely recommendable.
