We had a great time in Prague! Accommodation was great, sparkling clean, with well equiped kitchen and location was 2 minutes from Wenceslas square. There was basically no need for us to take any transport, everything was in walking range, Old Town supper close, Prague Castle relativelly close, we even walked to Vysehrad and Petra's Tower.
The only issue we had was with the heating which wasn't working properly, but we had a great communication with Alex and Tanya and repairman came a few times trying to fix it but it was only fixed for a day. This was a bit incovenient in the mornings as it was November, but we usually spent whole days out anyway.
