Mark and his staff were excellent hosts. They were all very pleasant and provided a wealth of knowledge about Prague, providing maps and recommendations for dining and activities. He even booked us a driver from the airport which was above and beyond.
The flat was clean and spacious. Exactly as pictured. Within easy walking distance to Wenceslas square and all public transportation. Old town square and that area are also walkable, however, know this flat isn't right in tourist central (which was a nice thing for us). Excellent air bnb. Would stay again and highly recommend.
