We were here in summer and it was very hot. The fan does very little to alleviate this. Very good location though, with a supermarket, nice bar and restaurant near by. Close enough to walk into the centre of Milan. However it is quite noisy - throughout the night and early morning - with smashing bottles from what we assumed to be a recycling plant or similar.
The bed wasn't really suited for 2 people. Particularly in the heat.
Other than that the flat was well kitted out. I would stay here again - on my own, but not as a couple - as is unsuitable for two.
Host was friendly and helpful.
