We stayed at Alex and Kate's apartment for a stag party and it was perfect for the 11 of us that stayed there. All beds were comfortable and there were enough towels also, a small but important thing! The location is perfect! close to bars, shops, restaurants and tram stops. I sent a couple of messages to Alex and Kate during our stay and they replied in minutes both times which i really appreciate.
I would reccomend the apartment to anyone with a group of around 10 who want to visit Prague, a great apartment in a lovely city!
