Hosts are pleasant and helpful, they were ready to meet us even though we came late in the evening. The appartment is nice, but not very modern, bathroom is good, location is great really close to the center and major touristic locations like Tiergarten and Charlottenburg + close to both metro (U and S-Bahn)
Kitchen is small, wifi is weak though. Not a good choice is you plan to work there.
Generally I would recommend it, maybe a bit overpriced, but comparing to much more overpriced appartments of Berlin these days, it’s quite affordable.
