Great location. across the road from the metro, but not noisy. funky little area but a fair bit quieter than some of Berlin's more youthful or bar/nightlife areas.
Room itself was great. Booked a double room (for me and a friend) and there isn't a lot of privacy for the shower - no problem, but a heads up.
Clean rooms, nice air-conditioning. Beer in the fridge on arrival, great spot!!
Easy check-in/out.
