Generally it was a quite cheap apartment to spend a few days in Prague. We didnt meet our hosts in person, we communicated by messages but that is their general policy. Although we found the floors of the room a bit dirty, there were little insects near the door, we found the drainage of the bathroom a bit smelly and the shower drain was probably half-clogged because the water was very slowly flowing away.
Finally the transportation to the center of Prague was very convenient day and night (10-15 min by tram, 30 min on foot) and the code system they have installed for entering the whole building and the room, instead of using keys seemed to provide great security.
