Ahmed didn't do the checkin himself, but had someone else do it for him. Checkin procedure was very easy and pleasant.
The location is 3min from Marienplatz by foot. In the summer the apartment becomes really hot, since it is at the very top floor. However there are ventilators in each room, that also chill the air.
The carpet isn't quite what you'd expect for 150€+/night, as well as the smell in the apartment. However I very much prefer it this way, than trying to obfuscate it with artificial fresh breeze or the like. The bed was very comfy and definitely the most positive thing in the whole apartment.
