Communication with George before arrival was very easy and fast by airbnb e-mail.
George picked us up from the airport. He also requested for us a taxi on our way back to airport.
The apartment is clean and mostly everything we needed was there.
An excellent location to explore the city - a few steps away from the Charles bridge, the castle, Kafka's museum and one of the main metro stations (Malostranska), little parks and a lot of restaurants are all very near by.
It is a very quiet area, there is no noise from the streets preventing you to sleep at night.
I certainly recommend staying in this apartment.
