Positive: Lovely, clean apartment in a quiet neighborhood with good access to amenities. Close access to U3, Ku'damm, Bahnhof Zoo, etc. Nice walk to Savignyplatz.
Negative: There is one bed and an uncomfortable fold-out couch. This did not match the listing description. I met the host in person on the last day of an 8-week stay. He was lovely, but in our electronic communication, he had accused me of bringing additional guests and not telling him the truth (my reservation had indicated 3 people, and we were 3 people the entire time). This really discolored the experience.
