Ok, these are just the facts about this apartment. You can use them to decide for yourself if you want to rent it. I stayed in this apartment for one month so this review is from a long-term stay. First, the good:
1. It's 5 minutes from Duomo. So it's literally in the center of the city.
2. It's a large apartment that can sleep five people.
3. Good wifi.
Now, the bad:
1. This apartment is not a loft. It is a street level apartment that a bedroom was created by using part of the upper part of it.
2. Because it's on the street level, if you open any windows it's a bit noisy in the daytime.
3. Because the bedroom was created by placing a floor half way up the apartment the ceiling is very low. I am not a tall person and I hit my head on the beams a couple of times. You have to bend over to walk around the bedroom to not hit your head on the roof beams.
4. The kitchen is very small, actually a kitchenette. The fridge is like a small one you find in a hotel room. (While I was there, it barely worked.) If you plan to do a lot of cook, you will find it challenging. It's find to heat up food or cook basic stuff.
5. There is a ventilation duct in the bedroom makes a howling noise and you can't turn it off.
6. The sofa bed in the living room can sleep three people but it's not very comfortable and you can't block the sunlight in the morning.
7. You should be aware of the no refund cancel policy and the check in before 9pm policy. I didn't pay attention to these and could not cancel the reservation and then when my flight was delayed I ended up arriving in Milan at 11pm and had to book a hotel to stay the first night.
8. Even though I stayed there for a month. The host never offered to clean the apartment during that time or change the bedding. I had to wash everything and clean the apartment myself.
If these things are not a big deal for you and being in the center of Milan is and you can afford the price then it could be fine.
