We were 3 people in Fiammetta's apartment and it was very comfortable and clean. Check in and check out was very flexible, we really aplreciate it. There is everything you need to stay there, the kitchen is super full equipped. Only the pillows were a bit uncomfortable, but we slept well because it was very calm at night. It was also great to have AC in every room because outside was very hot. 2 min to the metro station and in 10 min you are in the centre.
I recommend the apartment for short and long stays in Milano!
