Mirko's appartment is perfect for a couple, no more. It is on the 1st floor of an old, nice Prague building. Very easily reachable (metro Muzeum), just on top of Wenceslas Square, so pretty well located. Most of the main touristic attractions are within walking distances.
The flat is on the speed way going through the city (a communist heritage) so not so easy to park with a car (taxi for example) but manageable. Very functional and well organised flat, very quiet on an internal/inside yard.
Mirko was flexible on arrival and departure times, and thoughtful while we were there (big floodings...).
