Staying at Carolina's place is great. Perfectly located in trendy Palermo, it is pretty easy to get around BA using her place as a base.
Carolina is a perfect host. She really went out of her way to help us (recommendations for coffee, drinks, nightlife etc and helping provide laundry coins) which was amazing and most appreciated.
The home is lovely. Good sized bed, great shower and simple cooking facilities, and though we weren't able to use it this time, there is the pool which was a great bonus.
If you visit BA, we would certainly recommend staying with Carolina and have a wonderful time!
