I can't speak highly enough of the B&B San Siro - the hotel is nicely decorated, clean, comfortable and convenient. If you're attending a game in the stadium I challenge you to find a better overnight option.
If you have a room facing to the West, you should be able to see the players' entrance where they drive in, which provided good entertainment for us in the run-up to the match.
Breakfast was great and there are good food options including the diner next door.
Also the hotel team were really helpful when we left an item behind - we managed to send a courier and recover it in good time. Andrea on reception is a legend!
All in all, fantastic
