Ray is a very sweet and special person, very helpful welcoming and open. The room is cosy, warm and vintage. The neighbourhood is very nice and alive, there are two Ubahn stations at 5/10 min walking distance, and lots of cafe and restaurants. I've been there for one month and a half, felt very well and enjoyed very much my stay, only had some problems with the internet sometimes but I know is getting fixed, maybe check to confirm if it's important for you. It's a first floor so the access is super comfortable ;)
