This place is a good one for visiting Prague. Very accessible as the metro is almost literally across the street from the apartment. Also, it is in a very cool part of the city with lots of restaurants and bars nearby. All tram lines also run by the apartment and basically do so all night. You can even walk to the old city from the apartment in about 20-25 minutes with lots of things to see on the way.
The apartment, itself, is clean and has all you need to be comfortable. However, the beds are a bit too small. I also think the host could be a bit warmer in his communication, although the communication was prompt and adequate.
All in all, I would stay at this place again and I recommend it!
