It's normal apartment with all you need inside it but I am not sure about AirBnb PLUS status of it. Location is great, the metro is 5 min from it and by foot you need 30-40 min to reach Duomo (for example). There are everything you need inside to make food or even to wash your clothes. Nevertheless electric kettle was old and hair drier too. Furniture, linens, pillows etc is basic IKEA. Two bathrooms was great. There is locker with keys which makes your check in and check out comfortable.
The main two things which make us feel uncomfortable is a high noise from early morning in working days (8 a.m.) just behind the wall in the bedroom. You just can't sleep anymore. Because it's office in there. Or beauty salon, something like that. You feel yourself in the center of laud dialogs and loughing. Very annoying when you come to have rest and sleep for some long time. The apartment is surrounded by two offices.
Other thing is construction process in the garden. Which is noisy too. But hopefully not all day long.
There is very small amount of sunlight in the apartment, because it is located deep inside the high building so it's always a little bid dark there. But if you will come for just a couple of days it will not bother you I think. For a long period of staying it's a little bit hard.
