We did a really short business trip to praha and some of us stayed in Ancap's apartments.
Sofiya took care of us and was always there for questions and tips (and fast). She even did organize a restaurant and the shuttle-service - all went perfectly good. The appartment had everything we needed and had a really cool and nice interior furnishing (we even enjoyed playing some ps4 and the beer-tip was great too :-) ). The apartements are close to Praha 1 too.
Praha itself is a really beatiful city with nice architecture, interesting history and nice people. For me i will definitly come back for a few more days.
Thanks again for having us and i wish you a happy new year.
