This is THE perfect place to stay in Berlin!!
Very well located, quiet, close to metro station to the center and all commodities, very spacious, we just felt like at home. The half-basement situation keeps us cool in the warm berliner summer, and the garden was very (very) appreciated.
We didn't meet Ralph, but it's very easy to communicate with him, and his friend Betty was here to help for everything and give some very good tips!
For sure I would come back at Ralph's place! Thank you!
