We had a pleasant stay at Oleg and Katrina's place. It was very easy to communicate with bothe of them, and they provided us tons of informations about how to get to the apartment, what we'll find around, how things work there, etc. Thank you very much for being so thoughtful.
The apartment is at a perfect location, 2 minutes from the Old Town Hall Square and it's ina very nice, tidy neighborhood. On the weekend it can get noisy at night, since party animals are all over Prague lately. :)
Anyway, it was a very nice place, we would definitely recommend it.
