Overall we liked the flat. Paolo is very friendly and was always available for help.
The parking spot is in the basement, so your car will always be cool when you go on a ride. Also parking is usually not free in milano, also not in this area...
The house is located in San Siro, very close to the huge Stadion of AC Milano and Inter. There have been one or two games i think, but it was no problem/ not very loud. The area is a very luxurious residential area as stated by paolo. Most houses are similiar to the one, the flat is in.
It is not exactly in the center of Milano, but you can definately get there within 15 minutes.

The flat is huge, probably around 200sqm and has very luxurious interiour. It is not especially new, so some parts of the furniture are broken, but this didn't really matter, because you can still feel, that this place used to be very fancy. For example, the kitchen has an abandoned food elevator, and you can ring a bell in most rooms. (so that your attendants know, you want something.)

As stated before the kitchen has a gas stove. Someone complained about it, but we used it daily and there were no issues.

However the kitchen could have more equipment.

The TV is a rather new model and has many italian channels.

The pool was not heated, but therefore quite refreshing. It wasn't used by anyone but us, so it rather felt like private than a shared pool. It is quite large. There are pool times: two hours in the morning and two in the afternoon. We usually followed them.
The water was not chlorinated but the pool was cleaned daily.

I suspect that this not the case for all pools in the area, since there were many mosquitos. For those sensitive to mosquito bites, i strongly recommend to bring mosquito repellant and to take care of when to open the windows.

The house has a very friendly custodian, who doesn't talk english, but was still helpful.

Overall I'd recommend Paolos apartment.
