We stayed here for a month, and we could not have asked for a more perfect place. Right on the plaza, near great food and bakeries, so easy to get everywhere else. It is extremely private and the building is as charming as it gets. We got to know people in the neighborhood and it felt like home. Plus, Mara was very helpful when needed.
Biggest perk: the apartment is a three minute walk to Rosetta Bakery (and not a one minute walk, or that would be dangerous for my health).
One note: it's a three-flight walk up to get to the apartment, which was welcome for us, but could be difficult for others.
