The flat is in a good location. It is in an older building which was under repair while we were there. There was no water during the day. Jan offered us a different flat, but the alternative had no a/c, so we stuck it out. The flat is small, but it works well as a base to explore the city.
Jan asked us to call him when we arrived at the train station, which we did. We had to call him again when we got to the apartment and wait another 15 minutes for him to show up. Luckily the weather was ok, but this cut into our short time in Prague. He also insisted on meeting us in the morning to check out, which would have been fine, but he showed up 30 minutes early and sat in the flat while we finished packing and getting ready to go.
