Michal kindly gave me a lift from and to the airport at a good price; the apartment itself is situated within walking distance to Prague Castle and Charles Bridge; very clean and suits 2 people well. There is tram stop nearby; underground metro station is about 10 - 15 minutes walk. There is nice view of the castle from inside the apartment.
Communication with Michal was easy and fast; Michal speaks English pretty well and is a nice and assistive person. I will certainly stay at Michal's apartment again.
Thanks Michal for your hospitality.
