The room we selected had 4 twin-sized beds. It was clean, and the room spacious enough for us to stay in while we were not exploring Prague.
There was some construction in the courtyard, which started early, but our host was gracious enough to share some Czech snacks with us to apologize.
Our host was also willing to let us check in a few hours early, which was great for not having to haul our luggage around (or use the lockers as recommended in the pre-stay .pdf).
The location was nice - close to the train station for easy in-and-out of Prague - but far enough from the more tourist-centric areas to get a feel of Prague life.
Our host also spent a good amount of time with us to introduce us to the city, and make a couple of recommendations on restaurants, beer gardens, and bars.
A wonderful stay in a wonderful city!
