I tend to see this place basically as a well-sized studio; if you are alone or a couple, it is grandiose. We stayed there a couple with two young children, and it worked perfectly also for us. For other setups, it may be a bit more challenging. Excellent location: very nice, calm corner of the old city, with good access to public transport (only one bridge to cross with your suitcases). It is in a superb old building, an apartment recently refurbished, tastefully and with a very good eye for details. Well-sized aircon capacity. :) We did not meet our host, but had a good and efficient communication.
Maybe just one thing: beware of the low ceiling. I am 185, I like high ceilings -- and it still worked well for me, thanks to the skillful architecture. However, if basketball was already your sign in the kindergarden, pls consider it. Otherwise, I can warmly recommend to all who appreciate quality.
