I booked this flat 1 day before I went to Prague. So our expectations were pretty low, because almost all other options were already booked. The check in was super easy and not complicated at all thanks to Gabrielas great description. The apartment was way better than we expected. It has literally EVERYTHING you need and it is super clean. The location is not directly in the city center, but 10min away is a metro and a lot off tramlines.
All in all, it was a great spontaneous stay :)
