Ksenia and Art were very nice, and always replied my messages quickly. Even though they could not welcome us, a friend of them was on the spot when we arrived at the apartment and was extremely helpful. The apartment is just like in the pictures, cosy and clean. Finally, the neighborhood is lively and safe, nice restaurants around, not in the center, but very well communicated by public transport, so it was very easy to arrive at Prague's main attractions.
