The Villa Giannino apartment was very clean and adequatly equipped. But the absolutely best place is the patio. It´s huge and the view is stunning, among top 3 that I have seen during my 3 holidays in Italy. The steps down/up are really not any problem.
Ravello is a beautiful, little town. There is not much to see but we also enjoyed a few days just reading and relaxing on the patio and in the evening we went out for a dinner. There are many very good restaurants but I recommend to eat e.g.in Amalfi town as well. We think that the food in the Amalfi area was the most delicious in Italy.
The only negative thing was with the loction that from Ravello it takes always 15-30 mins until you are down by the sea in Amalfi and the buses were sometimes really full. ( Well, then you would miss the view :) And also not any good grocery store in Ravello. The ones that are have robbery prices.
But if you choose Ravello, the Giannino is very good choice.
