We had a great time staying at German and Elena's place. The apartment is huge and even nicer than the photos, it was warm and the beds were comfy. good wifi and smart tv. We messaged German as we were leaving the airport in an Uber, and he was waiting for us outside the apartment when we arrived to welcome us in person and show us how everything worked etc.
The location was great, five minutes walk from two metro stations, the trams and there were lots of cafes and restaurants right on the doorstep. The neighbourhood felt clean and safe.
We would not hesitate to recommend the apartment to anyone coming to Prague, we would absolutely stay here again if we revisit the city. Thanks German for a great stay!
