Everything was excellent.
I visited Palermo this August with my girlfriend and we stayed for 5 nights. From the start, the host welcomed us and provided us with plenty of information about what to do in Palermo. Her replies were also fast in case we needed something.
The apartment was clean, really well taken care of, and plenty spacious for a couple. We had hot water 24/7 in the shower and A/C was also installed, both of which were really appreciated after walking in the city during August. The apartment was situated right at the heart of the city, which made it really easy to explore the area.
I would recommend this apartment to anyone who wants to explore Palermo!
