A very spacious room in a 'youth hotel', in quotes because I didn't see many other guests and can't really speak for the age distribution... Not exactly a youth anymore myself. The location is great, a couple of minutes walk from the Kleistpark metro station, and the check-in is very hassle-free, just get the key from a key-box next to the door. The room was clean, and exactly as described. The place fully met my expectations and I fully recommend it for a few days' stay when not interested in spending too much time at the accomodation. So, 4 well-merited stars only because I'd like to keep the 5th in order to have something to add for the truly exceptional accomodations. This one was simply very good.
