The apartment was brilliant to be fair! Even though it's right in the middle of the city it was still nice and quiet, and we didn't hear as much as a peep from the neighbours :)
The appartment itself was fantastic; It had everything we needed for our few night stay and the design was really to our liking.
Michael and Johanna themselves were great as well, they sorted us out from the airport to the apartment and had us dropped off literally at the front door. The instructions came to us with plenty of time to spare and were spot on so we got in with absolutely no hassle :)
Would definitely recommend.
