We were there for 4 adults and enough room. There is plenty of air coming through the large windows. The house is very well equipped and clean. The location is simply superb. The neighborhood is buzzing with a young people and the short distance to the metro station is amazing one minute walk (it was realy amazing). It is great to return to this house after a stroll through the streets of Berlin. It's just a feeling you're home. Warmly recommend the wonderful place. Andrea, of course, was amazing. He waited for us and the communication with him was amazing. Thank you very much. I'm sure we'll be back.
