Great stay. The apartment was in such a brilliant location, easily within walking distance to all of the key places - including old town, new town, Wenceslas Square, Charles Bridge, Jewish Ghetto, Mala Strana and up to the Castle. Highly recommend.
Host allowed us to leave bags after check out rather than carrying them around all day which was helpful. Post cards in the room were a nice touch too.
There was unfortunately some building work going on directly above us which was very noisy at 7am each morning, but this is out of the hosts hands and besides this our stay was perfect.
