The apartment was just as shown in the listing photos. It’s pretty basic but very spacious and has all the essentials covered. Francesco was easy to communicate with and met us at the apartment for check-in.
As we were arriving at night we found it a bit tricky to locate as it is not actually on the street that the address refers to. Instead you have to turn into a little piazza/courtyard with several buildings, one of which - #146 - houses the apartment. If you find the police station directly across the road you are there.
Although the building is adjacent to a busy road the bedroom and living room face the opposite way and the windows and shutters effectively keep it quiet.
The location is indeed a reasonable walk from the eastern end of the valley of the temples. It is a much longer walk - 4-5 km - if you go to the archeological museum first and then enter by the temple of Heracles. We two 70-year-olds did it without regret.
As others have mentioned there is a grocery store practically next door and several restaurants nearby. We had a car so went into town for our two dinners: one at Aguglia Persa which we absolutely loved and one at La Scala, also good.
Francesco’s apartment was excellent value and we were happy with our stay there.
