We stayed at Javiers flat with two, from time to time with four persons and felt really good there.The apartment is just as described, with room enough for six persons. The interior is a little minimalist but enough and all in all stylish.The location of the flat is just right, off the beaten track, but if you want you can go there quickly, cause the railroad connection in Berlin is simply fantastic. After trips in the city you can relax on the balcony with sight in a green court. I would choose this self-catering apartment at any time again.
Javier himself had a sympathetic ear for every question, was very courteous and kind.
