Had a wonderful stay at Radkas place. Thanks to my small folding bike, I went between the old town and the apartment with ease (10-15 min by bike). Never took the tram. The neighborhood is very nice, small restaurants and cafes around, very nice and tranquil atmosphere while lively at the same time.
The possibilities of cooking in the apartment is very limited, and didn't exceed boiling eggs in the morning. Small mini marts are close to the apt though.
There was one set of keys handed over at check in, and I never asked for a second set which could have been useful at times, since the entrance door opens with key (not code) and the apt is at the highest floor.
Overall a very nice experience in Prague, thank you Radka!
