The flat was neat and very clean, the check-in super easy and the communication went very well ! We were recommended some nice areas and restaurants on the first evening (including the best ice cream we have ever had) and in general the owners were really nice and courteous.
The only thing was that the water didn't really get warm and that we didn't know at first that the room was part of a larger flat, of which the rooms were rented out.
But all in all the flat is perfect for a short trip to Milan !
