We stayed 4 nights at Vaclav's place. The whole apartment and our room were very clean and well organized. You can reach the city by bus or tram in 15 minutes and if you're not in mood for sightseeing, stay home and relax in your comfortable room with the tv. Vaclav is a really nice and charming guy. If you have questions, don't hesitate to ask him. He has the best tips for sightseeing, money exchange and secret places loved by locals (ask him for the best spot to see the sunset ;) ). If we come back to Prague, we definite will book Vaclav's place again. :)
