I did not meet Ondrej, I was welcomed by another man who spoke little English but was still a pretty effective communicator. He showed us how everything worked and did his best to help me contact the airline when my flight was cancelled by the airline at the last minute - unfortunately they closed at 5:30 PM and they cancelled my flight at 7 PM. The location is great - tram and subway are a very short walk away and the grocery store is as well.
Ondrej left a list of restaurants to try and we tried Jama which was very good and close to the apartment.
The only thing we didn't like was that the apartment was above the outdoor garden restaurant and the cigarette smoke would come into the apartment when the windows were opened. There was a heatwave in Prague at the time and not being able to open the window was an issue for us. The stove and refrigerator also need a good cleaning, but otherwise the apartment was clean.
