First off, the group/individual that owns this apartment and rents it out is incredible!!! They were great at communicating with me, and check-in and check-out could not have gone any smoother.
The location is really close to the train station, which was nice, but was a little loud. Because it's a little further away from the square, it's darker at night, so best to travel in a group (but that's goes for most places in Prague). I stayed in this apartment with 9 other people, and while we definitely fit and all had a bed, I think it would be best to stay with 8. The shower was our only main issue because it's really a bathtub with a detachable shower head. Other than that, everything was very clean, and we really enjoyed our stay!
