The apartment was really pleasant and exactly as described/pictured. It is really well-located--it's very quiet and peaceful but conveniently connected by S-bahn, U-bahn, and tram to really everywhere you could hope to go. Check-in and out was convenient and easy.
Although Ellen was not especially friendly in her communication, she was prompt where it mattered. I kind of missed the personal touch but the apartment was well-located and nice, so I'd absolutely recommend it and would probably stay here again.
