We stayed for 10 days, working remotely for most of it and thoroughly enjoyed ourselves, the internet was very reliable.
The apartment is so lovely, it has been decorated to feel more like a lived in home than an Airbnb. There's a lovely breeze for most of the day if you keep all the shutters open, Palermo was very hot during our stay and we hardly used the aircon at all.
Elina is lovely and attentive, the perfect Airbnb host.
The surrounding area is a little rough around the edges, but it's only a short walk to get to restaurants, shopping and the sights.
