We had three nights in Prague. The flat is big, clean and nicely decorated. The bathroom takes a bit getting used to as it does not have a door, just a curtain but it's no big deal. Also the hand held shower faucet is always a challenge! The flat is centrally located and we walked everywhere. It's also just a short tram ride away from the train station. Mark is very helpful and responsive. Definitely try Home Kitchen for one meal. It's just around the corner from flat.
All in all we had a nice stay and we recommend the flat.
