I had a great stay at Martina's apartment. She was a kind and friendly host, offering me cake on arrival (!) and letting me move in earlier than the advertised arrival time, which was much appreciated given that I had to get up at 4.30am on the day. The flat itself, in a stylish century-old building, was very much as described, the kitchen was well stocked with equipment, and the room itself was light and spacious, with a comfortable bed. The flat is well located, near Implerstrasse U-Bahn station, with a bakery and supermarket opposite and a nice pool (Südbad) five minutes away. I'd recommend it highly.
