I stayed here for almost a year and I can't praise it enough. Stefano and Marisa are wonderful and outstanding hosts. They were both very thoughtful, kind, and always ready to address any kind of questions, suggestions, or advice. The apartment is in a great location, with all public transportation nearby. It's also very stylish and extremely well equipped.
This is the best airbnb experience I've ever had, and I would recommend the flat to anyone looking for accomodation in Milan, for either long term or short. I'll definitely be back, next time as a tourist :)
