Kateřina was very helpful and nice.
The apartment was very clean and felt very luxurious.
The area suited us perfectly as we wanted to stay a little bit outside of the tourist places and experience the city as a local resident (it was still close to the center about 2-3 km which could easily be reached by for example the metro).
If you are going to visit Prague, I highly recommend that you choose Kateřina as your host.
