Well the apartment is not the cleanest, or the newest one, but let's be honest, it's one of the cheapest in that location, so it's good value for the money. Things I really liked are: the location (very central, most of the attractions are reachable by foot), it's so close to metro, tram and bus station if you want to use public transportation; the heating is good although the heating restrictions across the Europe, you won't be cold. Also the host provided to us some useful tips like good pubs, clubs and food. I won't write about the things I didn't like because I think it's very individual. However, we all go to airbnb apartments in the touristic citys only for some hours of sleep, so I think it's okay to book this one if you want to see most of Prague for short period of time.
