Fabulous location on Piazza Bologni only five minutes from the Cathedral with a delightful host. Very clean apartment in an heritage building with original beams. The main bedroom had a small balcony onto the piazza where you could watch the world go by.
As mentioned by other reviewers, we were invited to go on a tour of Andrea's family palazzo which was very interesting and gave an insight into Sicilian nobility.
We took up Andrea's suggestion for a v good restaurant with authentic Sicilian cuisine (14 mins walk from the apartment) and he was right. Lots of cafes and bars close by if you don't want to walk.
Only basic cooking facilities in a small kitchen and it took a while for the rooms to heat up in mid-winter but I can imagine it would be cool in summer.
There's no Wi-Fi but I got it from from the restaurant below (nice but pricey). The other thing that was important for us is that it felt very safe being in a secure building with no dark alleys to walk through to get there.
