I have spent 4 months in Jole's apartment and I have really appreciated living there.
The flat is very clean, with all the functionalities as stated in the description: microwave set, air conditioning system, good Wifi connection...
The concierge operates from Monday morning to Saturday evening and she is really nice and always available whether you need anything.
Moreover, the apartment is very well located. Metro and tram lines are all within 3 minutes walk so you can go quickly to the Piazza del Duomo (15 minutes) and to the central station (20 minutes).
It is also close to Bocconi University: only 15 minutes walk or 10 minutes by tram.
Finally, the host is really pleasant and very responsive when needed. She is also available to give you recommendations on great places to visit in Milan and its surroundings.
All in all, I strongly recommend it!
