If you are looking for a clean, quiet apartment in a good location, but without the Airbnb personal touch, then Markus's place is for you.
Mind you, there's no central heating, just electric fans, so bring something warm to wear in.
Also, the amenities in the ad don't cover what's there necessarily, so make sure you don't run out of toilet paper ;-)
The apartment and the location are very good, but there's no 'insider tips' whatsoever. If you don't mind the latter, then I can definitely recommend Markus's apartment.
