I booked this apartment for my 4 days trip in Prague with my friends (7 ppl) and we loved this place! Everything look like in the photos.
Perfect location in downtown : Wenceslas square is like 3 minutes walk-away from the apartment. There are subway/tram stations, restaurants and grocery stores close by. We visited the main sites of Prague on foot. The only time we took the subway was when we were leaving to the airport.
Also, we were well received for check-in. Kai was very friendly and gave us addresses to good restaurants, bars, and places to visit. That was really helpful for planning our stay.
Definitely recommend this place ! ;-)
