I stayed for a week at Anne&Axel's apartment in Gaudystrasse and it was great! The place is clean and tidy, very nice decorated and well equipped. The surrounding neighborhood is also very fun and viable - great public transportation: U+S bahn stations, trams and buses, lots of restaurants and and shops, supermarkets and everything i ever needed. Anne&Axel's were very nice and generous with my check-out time and im great-full for that. Thanks also to Anne's dad, Paul, who showed me in when I arrived :)
I would definitely recommend their apartment for my friends and would love to be their guest again!
