A few minor hiccups to begin with, starting with the ride from the airport and the pick up location for the keys, but the hosts were extremely responsive and helpful. Alex and his team were very professional, and he gave us an extremely thorough introduction to the city, with quite extensive guides in the apartment as well.
The apartment was located within minutes of the city centre, yet was quiet enough for us to get a good night's sleep.
Alex and his team were also very responsive to questions and requests, and did their best to make sure our stay was as comfortable as possible.
Overall, one of the best experiences we've ever had, and definitely made our stay in Prague more memorable!
