The flat is wonderful; although Brera is noisy on the streets, the flat is totally quiet and the court-yard is very pretty. Its location is great. A lot of great restaurants are nearby, as is the park if you want to go for a run. Most sights, including the Scala, are in walking distance.
It's a good place to stay during the yearly furniture fair because a lot of shops and exposition spaces are nearby.
Sabrina was a perfect host, very flexible when everything went wrong with our arrival, and communication was quick, easy, and very friendly.
Would stay there again.
For Germans: The German Consulate is ten minutes by foot as are the Carabinieri, which may come in handy...
