We loved our stay at Marek's apartment and would definitely stay again. He made it an easy and stress free stay from the moment we booked. He was very accomodating even when our flight to Prague was 2 hours late arriving, and let us checkout late since our flight home was in the evening.
The apartment was clean and had everything we needed, it was in a nice quiet neighbourhood and close to the city centre. Marek gave us some loads of information, useful tips and great recommendations that were less touristy.
I would definitely recommend staying here.
