We were a party of 3 couples and we arrived in Milan in the evening for a night's stay. I messaged Susanna and came to meet us at her place. She gave us a warm welcome and showed us the apartment. The description of it is very accurate. The location is great. Neat the Milano Centrale railway station and very beautiful neighborhood. The apartment its self was immaculate clean, warm and tidy. Even though we stayed only for one night we really felt welcome by the owner and we 've enjoyed the amenities of the apartment. Only downsides for me were that the two bathrooms are inside the two bedrooms, so if there are 3 couples like us, one couple should be ready to leave the door open so the occupants of the other bedroom can use the bathroom. This wasn't a problem for us since we stayed only one night but it might be a something to consider in a longer stay. Also, one of the three bedrooms has folding single beds and not proper ones. My friends that stayed in this bedroom didn't make any complaints about them being uncomfortable. Lastly, my wife and I used the bedroom with the double bed that faces the road in front of the apartment. It is the most beautiful one but the is a tramway outside and you could hear trams passing every few minutes. We did have a good sleep but someone more sensitive may find it disturbing.
I would suggest Suzanna's apartment is more appropriate for 2 couples (definitely not for 3 couples) or a group of 6 friends and I highly recommend it because I liked the neighborhood, the location, the cleanliness and the decoration of the apartment and the welcome owner.
