We stayed for a week and were very happy with the apartment: It is spacious, well equipped, stylish and in an absolutely perfect location. I can fully recommend it to anyone.
There are minor disadvantages: The windows to the main street don't keep out much noise (but you're in the middle of the city) and there is no elevator (but you're in a lovely historic building). These two issues weren't a problem for us, but they might be for some. We fully enjoyed our visit and would re-visit anytime.
