Casa Manfredi at 48 Ricasoli in Palermo is a gem. It's decorated beautifully and has a lot of character and quirkiness. It's small, but it didn't feel that way at all because the space is used cleverly. The bathroom is great, the two bedrooms with their own balconies are fantastic, and you can tell that Francesco and Luca put a lot of thought and care into making it into a sweet vacation home. We were never more than 15 minutes from anywhere. It's located in a great spot near the center. In regards to communication, Francesco responded to every question almost immediately. I never felt like I couldn't ask him a question. Also, we arrived around 11 pm to the place, but it was not a problem at all for the hosts. They will go the extra length to make your stay as comfortable as possible.
If I ever came back to Palermo, I would definitely try to get this place again.
