I had a great stay in Milano in the appartment. The appartment is situated in a nice old building with a view on a typical Italian courtyard. The facilities inside the appartment are good, clean and everything as you can expect. Breakfast is just cereals and coffee, but for me that is OK.
Be aware though that there are costs for linnen for the single beds (25 euro per bed), since the appartment is apparently "rented as a double only" you need to pay extra for that. I was not informed about this in advance, although I had indicated I was going to stay with my brother and they could have assumed we would not want to share the double bed. Unfortunately the host was not responsive to my comments about it later.
In general my stay at Andrea was good and I think it is good value for money.
