This is a great apartment that is literally one block from the Duomo. The hosts Paolo and Samuel were excellent communicators and very responsive. The space is perfect for up to three people. The kitchen is modern and well-furnished, and the main bed was very comfortable (the other bed was a pull-out couch, and not as comfortable, but fine for a few nights. The wi-fi handled multiple devices that were streaming videos, though it was slow at times.
There was a problem one evening when it rained: The old windows were not caulked very well, and water started leaking into the room. They said they are going to fix this, and I assume that this has been done. Other than that problem, everything about the space and location was wonderful!
