Fantastic spot! My parents and I stayed at Salvatore's place for about a week. The flat definitely met expectations, it was new, clean, and very nicely furnished. We had more than enough room, with my parents staying in the main bedroom, and me in a lovely alcove downstairs. The location couldn't be better, just a couple blocks from the sea and from the piazza.
One evening there was some loud music coming from the local restaurant downstairs. However, this leads me to the next point: Salvatore was more than eager to help, always available with very (very!) prompt replies and action. From the beginning, he actually said we could call him if the music was too loud so he could ask the restaurant to lower it down. A great host!
Overall, I would definitely recommend staying in this flat, and actually hope to go back sometime soon!!
