Our stay at Vaclav's place was great! He is a really nice guy, always asking if everything was OK for us. The location is really good, between 5 to 10 min to Charles Bridge and the Old Town Square by tram. The neighbourhood is just as good, with restaurants and markets nearby. Praga is a wonderful City and he gave us tips and directions for "where to go and what to do" during our 4 days stay.
The room is really spacious and confortable. We strongly recommend staying there!
