Great place, big comfortable, with everything you may need for your trip. This kind of places is one of the reasons I don't do hotels anymore.
Fantastic area of Berlin (more so if you're a member of the LGBT(and friends) community. Close by to the u station getting you easily anywhere you wanna go to in Berlin. Mechthild (Andrew's mother - who toke care of things in his absence) was fast to response and very accommodating making my arrival easy and my mind at ease.
One thing to note though to really take under consideration : there's this oversensitive to noise neighbor who will make an appearance if quite is disturbed - so if you're hyperactive as I am you may yet get to know him better ;)
