Alessandra's place is super cute and uses space very well! It was perfect for me as a solo traveler and I think would be good for a couple but probably no more than two people. Alessandra was very nice, and excellent at communication before and during. She also has an impressive binder in the apartment of everything you need to know. When I arrived she had a basket full of food for me which was amazing as I didn't get in until 8pm and as soon as she left I literally cooked up the pasta from the basket to have for dinner.
I was worried sleeping on the pull out couch but its actually pretty comfortable and between the electronic blinds that can come down in front of the balcony door and great air conditioning, it makes for a very nice sleep.
The apartment is close to a lot of restaurants and I popped over to Vanilla Bakery for lunch literally two steps outside the door on the other side of the street. Otherwise, the metro is right around the corner and for 1.5 euros, you can be at Duomo in 10 minutes.
While I was there the apartment building happened to be doing some renovation but it wasn't a big deal. The workers started at 8AM and leave by 5PM and don't work on the weekends. I'm sure the work will be done soon and Alessandra would keep you posted on that if you had any concerns.
I would definitely stay here again, actually I would have looked to extend my stay but someone else snagged the room before I could do so :)
