The place is exactly as described: a cozy studio in a very central area of Milan. It is located about 5 minutes walk from the the red subway line, there are cafes, restaurant and a large supermarket within 5 minutes walk, too.
The studio is fairly large, in particular because there is a separate entry area for storage and wardrobe that allows the place to be more open. The bathroom is standard for Italy, with shower and bidet. He provided soap bars and some shampoo bags.
The shower door is a bit difficult to open at times.
As a plus, there is a washing machine, that I did not use, though.
The kitchen has 2 electric burners, is very efficient, IKEA-style, and there are cups, glasses etc for at least 3 people. He has a mocha machine for italian coffee, which is standard for Italy. There is a nice fridge, too, very new.
He left some cookies, toasts, ground coffee and nutella for us on the dining table. The bed is a double, very comfy. The place has an AC but I did not need to use either the AC or the heating.
The communication with Lorenzo was very easy. I speak Italian therefore we spoke on the telephone, but he also messages very quickly. Overall experience very good. Only thing to be aware: the place is on the 3rd floor (2nd floor for European system) and no elevator, therefore not suggested to people with disabilities or problems with walking.
The place is very quiet, in a side street and you hardly hear a noise.
