You really get what it's advertised. The flat is spacious, clean and bright. Jiri's brother waited for us in front of the flat with the key and gave us tips about the city. We felt very welcomed. We also liked that Jiri was available and helpful when we couldn't figure out how to change the heating, he gave us good instructions.
The location is perfect, in walking distance from everything.
There is a school in front of the flat and you can hear the kids playing during the weekdays, but it's not very loud.
