Silvia's house is in a great location and we enjoyed the use of the lovely terrace and despite being at the center of the city it's very quite.
However we felt that there were a few things that could be impoved.
As frequent Air B&B users we are used to finding at least a bottle of water as a small welcome- in fact there was no welcome whatsoever in Silvia's house.
We found the selection of bathroom towels rather poor. The pillows are lumpy and far too thick, they definitely need changing.
The bedside lights are too dim, impeding any bedtime reading. Bedside tables are wobbly and far too low. Finally there are not enough sockets for recharging technology.
Overall we would suggest a little more attention to the wellbeing of the guests, like maps, places to eat and general advice about Palermo.
