Our stay was really perfect!! Although Jiri and Kate were out of town and we never met, communication was great since the beginning, they gave us directions on how to reach the apartment from the train station and were to get the keys... the place is amazing, equipped with everything you need, plenty of space, very clean. The neighbourhood is nice and quiet, with lots of restaurants and bars. Walking distance to Prague Castle and 5 min walk from the metro station from where you can easily reach the city center and the bus stop to the airport.
I definitely recommend the place, we really had a great time in Prague!! Thank you Jiri and Kate!!!
