Very nice location, one block off of the main Piazza.
The apartment is all newly renovated. It's only big enough, I think, for two people. However, there is the other apartment on the same floor that you can rent from the same landlord. That's what we did. We rented both of them and it made one big nice apartment.
The landlord is extremely nice and has great communication. I really like staying here.
The only thing you might want to keep in mind is that he does not have a washing machine. Therefore, if you are on a long trip and need to do laundry, you might want to keep that in mind. But other than that, I don't think it needs anything at all.
