A great location right in the centre of Prague, only 10 minutes' from the train station and astronomical clock/old square. There were 4 of us in the apartment (2 adults in the bedroom and 2 teens in the main area, in two beds) and this was space enough for us.
Lots of helpful information about the apartment beforehand and some really useful local guides in the apartment when we arrived. The apartment had everything we needed and was quiet enough for us (despite it being just off Wenceslas Square). Thanks for letting us stay, Marek and Bara... we really enjoyed our time in Prague.
