Alex and Kate's place is highly recommended! Me and my friends are really happy and loved the place as it was clean and with big rooms. The place is in the safe area and surrounded with shops and restaurants of every kind. Asian resto and locals are around the corners. Walking distance to Wenceslas Square and thru there you will walk down to Old Town. Our first day was a bit messy as we are not accurate enough to read a map but then the following day it was made us easy to locate the places of interest. If I will go back in Prague I will definitely stay in this place again.
