Ronald's apartment is big and very nice, with all the amenities you could want, and it is located in a very nice and quiet neighborhood of Berlin, a little bit out of the center but very well connected with the rest of the city.
Ronald is a very kind and helpful host, he gave us a very warm, authentic and not at all formal welcome. He is also a very interesting person, it was a real pleasure to meet him and spend some time with him as well. Even when we shared spaces we appreciated his discretion and respect for privacy.
It is an accommodation I would recommend to everyone!
