We had a good stay at Frank's place. You'll have your privacy as it is basically a tiny apartment that is not part of the rest of the flat and it's big enough for a comfortable stay during a city trip. The bed is comfy and the sheets were fresh. The location was perfect, everything is easily reachable on foot and there's everything you need in the close vicinity.
The only thing I want to criticise is that it could've been cleaner and that the towels didn't seem to be the freshest.
