Rainer's place is really well located, and the room is cosy and had everything I needed for a short stay. The rest of his apartment is lovely, although I didn't have much time to enjoy it.
Despite my later than planned arrival, Rainer welcomed me and check in was super straight forward. The same with checkout.
The only improvement I could suggest would be a bedside lamp for night time reading, but otherwise all was good - comfortable bed, hot shower - all I really needed!
If you need a place to stay in Brooklyn, I would recommend!
