Eugenia's place is great! I was alone, so I had a lot of space, but you can easily stay there with 2 or 3 people. It has all the essentials, a good shower, a great bed and a very good (and silent!!) AC, which kept the place nice and cool during the hot days I was there.
It's in there middle of all the small streets of the old town, I had a bike, so it only took me minutes to get anywhere in the whole city, but also on foot you are close to great little restaurants, bars and shops.
Eugenia's brother Gabriele was the one I had contact with about check-in and if I had questions, he was very helpful and responded very quickly.
On Airbnb, Eugenia also responded very quickly. So all in all I would definitely recommend this place!
