The place is located very well - hard to wish for more to get most from the Old town, great food (restaurants nearby) and a 35min walk to the city beach.
It is also under the shade compared to some other buildings. Yet, if you travel in summer be ready for the heat. There are no airconditioners and only 1 small fan for this large apartment. So perhaps discuss with Salvatore this in advance to manage your expectations.
Be prepared to change your sleeping habits as the neighbours in the inner court and the passers-by are very loud till around 4 am in the morning. And the life resumes again around 8 am, so the quietest time to get some sleep may be the afternoon siesta if 4 hrs sleep is not enough for you.
If you need boiling water ask in advance about the electric kettle - we had to use the casseroles to boil the water for the tea.
If you intend to use the washing machine ask in advance if it works and how to switch it on.
Overall it is a very nice place in the Old Town.
Wifi was good.
The owner and his sister Eliana are great, very friendly, helpful and accommodating.
