We had a really nice stay at Andreas apartment! The communication was good also with his friend, how met us and gave us the keys. Everything went well and uncomplicated with the arriving. The flat is at a very lively and nice area, with a lot of restaurants and bars. Especially in the evening it's a nice and popular place to go. Even tough there are a lot of people on the street in the evening, we slept well, cause the room has the window on the backside of the building and you don't really hear anything. From the neighbours we haven't heard much either and we felt save and welcome. The flat is also good located, if you have planned to experience the city by walking and public transport. There is a metro station nearby, which we used, but we also walked a lot, which was totally doable!
I definitely would recommend that flat for a nice and short stay in Milan and we go there again!
