Everything was in place, promt replies, great reception and incredibly easy check-in & out. The place was super for us (4 guys) with its 4 bedrooms, small kitchen and a TV area + separate toilet & shower. Very centrally located, just around the corner from the train station, and a tram stop some 50m off. There is a quite friendly convenience store next to the street door, and a couple of excellent restaurants within 50-100m. Only downside to this place is the sound from the passing trams outside, but hey - that comes with the central location. The windows are soundproof, but as the apartment got quite hot during our stay (mid-summer, no aircon but fans) we had to keep them open once in a while. That was no big deal, though.
All in all, a great place to stay. I would choose this for my next trip to Prague.
