The apartment is clean and spacious. The furnishings are not deluxe but they are basic, serviceable, and well chosen: I felt more comfortable in Michael's apartment than the more expensively furnished apartment I stayed in elsewhere in Prague.
Michael's response rate on communications was excellent, which helped enormously, and Mirka, his cleaner, had the place fixed nicely for our visit (and we dropped off our luggage early, so we got to see it before Mirka had a chance to clean up from the previous guests; she did a great job for us.)
The location, which I feared might be too touristy or too noisy was neither. We were just far enough from the square and protected by a private courtyard; instead it was very convenient, with lots of options for food and sightseeing very nearby. Any time we wanted something (like a morning croissant or an afternoon snack or late-night take-out Thai food after a long day exploring) it was available within a block or two of the apartment.
We stayed in three AirBnBs during our time in Prague and although this was not the most expensive of those we stayed in, we enjoyed our time here the most.
