Nataliya is the perfect host. She was very kind and understanding, took care of everything and wasn't strict with check-in/check-out, which gives this place a great advantage over many others.
Another great advantage is that she is very responsive and offered to help in case of need. This is a big plus.
The apartment is very cozy - has a spacious shower and all the comfort you need (heating, small kitchen with accessories, hair dryer, even a washing machine!).
Location is perfect, in between two metro stations (closer to Pasteur). It takes less than 30 minutes to reach central station (both by walk and public transport). The area has grocery stores, bars (note: Scaringi offers vegan croissants) and restaurants very close. There is also a pharmacy.
The apartment was clean and I received fresh towels upon arrival. Soaps, shampoo and sanitizer were available. The Internet worked very well, allowing me to save on my already scarce mobile data bundle. Note that you need to walk some stairs to get there, not many but if you have mobility issues I'd contact the host for extra information.
I will certainly add this to my favourite places and I hope I will find it available for the next time I'm in Milano.
