We are a family of 4. We had a great time in Palermo. Silvia's place is very well located in a neighbourhood with a lot of local flavour and conveniences. Coffee and pastry is just around the corner, fresh fruit and vegetables are just down the street. All of the major historical sights are within easy walking distance, as are restaurants. Silvia was very responsive with communications and flexible (we arrived several hours early on short notice). Bedrooms, the bathroom and linens were all clean.
The apartment is in an older building in an old part of town, which brings some quirks. The main issue others may have relates to sleep. There may be noise from other apartments and some may like softer beds. There is also a bit of grime from the ages in the common areas.
Cheers,
