We stayed in Roberto's place for 3 nights and it was a pleasant stay. The flat is located right next to the best tourist attractions Palermo has on offer (i.e. the Palazzo Nomani and the Cathedral; don't miss the nearby church of San Giovanni degli Eremiti) and there is a free on street parking outside of the flat. The area is very residential but despite being so close to the main tourists sites it can come across as a bit forgotten by the city council. We never had any issues walking around, but on surface (I might be wrong!) it doesn't encourage single travellers on their own at night. The flat itself is very clean, spacious and recently renovated, and has everything needed for a comfortable stay. Roberto is great at responding to messages and he helped us a few times with parking-related questions, something we would not be able to easily find online. He also recommended a really good pizza place heavily popular amongst the locals. Many thanks.
