The apartment was exactly as described in the pictures. We didn't have the pleasure to meet Sandro or Ludovica in person, but still they seemed very lovely people. There was a lot of useful information offered (maps, booklets,...).
The overall cleanliness was very good, just some small things we noticed weren't perfectly clean.
The Santo Spirito area is really great place to stay to be surrounded by locals but still close to the historic center and lots of great dining places.
We highly recommend this apartment!
