We spent about 10 days in Bettina's place and loved it! It was the perfect amount of space to be able to spread out a bit and have our own space. Tough to beat having coffee/an afternoon glass of wine on the porch looking out on the Duomo!
The location is perfect for sightseeing since it's so close to the main downtown area, but the building itself is fairly quiet.
We'd definitely stay here again!
