Pros:
Geo location, all the contents the as described, lift, all the useful information being printed by the hosts.
Fridge, washing machine, hair dryer, fast wifi internet connection etc. all worked great.
Cons:
Terrible sound isolation. I'm actually surprised to read other people's reviews describing the flat as a "quite place" away from city hustle.
The flat is on the 1st floor facing the bar, we were able to hear what people at the bar talked about with windows fully closed.
From inside, the water pipes apparently being hidden inside the wall in the bedroom. Thus every time a neighbor open a water faucet or took a shower or used a toilet we heard it as though it's right near our heads.
Even more than that, the iron gate at the entrance to the building is right under the flat windows creaked so bad, I wished I had WD40 oil spray to apply.
Next to it is the automatic gate for a garage that creaked as well any time a car entered or left it.
Neighbour in the upper floor walked in heels till the late at night, occasionally dropping coins or smth on the floor.
Electric water boiler was barely enough for two of us to take a 5 minutes hot water shower each in the evening.
To summarize, we managed to sleep only somewhat between the midnight to 6 am during the all three nights we stayed in the flat.
I would definitely search some other potentially quiter place to stay next time I'm in Milano.
