Very nice place, VERY comfortable bed & sheets and just enough space for one or two people enjoying Berlin. great restaurants all around and Ulf will give you a long list and reviews of places to go see, eat, and do. There's a small kitchen with cutlery and ceramic ware and basic cooking items & appliances.
Though a bit involved to get into the place (3 doors before the actual apartment, it feels safer that theres some security. (though, the building door was left open on one occasion.)
Only possible con is that when you turn on the hot water in shower and sink, it can get very hot without much interval from turning the faucet to the cold side. also, the metal part of the faucet on the hot side will get scalding hot (this is not common in US, so I was very surprised). would stay here again & recommend to a friend but not if w a kid or a bigger person than I lest they get burned on accident.
Regardless, stay at Ulf's!!
