I stayed in Vilém's flat with my girlfriend for 5 nights. It is a very beautyfull apartment, located just 50 metres near the underground, so really functional. Just 6/7 stops to the city center, about 10/15 minutes. We couldn't meet Vilém, but he contact us for everything and send us a guide to find easily the flat (there is security service h24). I really really recomend Vilém and is apartment, super host at all.
