Betty's place was very clean and very spacious, an excellent launching pad. Betty herself was extremely responsive to questions and very helpful, plus it has a strong AC (a must when it was over 90 degrees Fahrenheit every day.) As my first stop in Italy it made things much easier because the place was so easy to get set up at, so clean, and SO easy to sleep in (super comfortable mattress plus basically blackout curtains).
The only thing to keep in mind is the the Milano Centrale area, while convenient for those traveling in and for getting to the train station, isn't really in walking distance of any tourist sites itself, and the best food in the area is mostly not Italian. That said the Metro in Milan is extremely fast for getting around the city.
