Francesco's place is excellent for travelling the Amafli Coast as we did when we were there. It is directly opposite the start of the train line which goes all the way to Sorrento! And getting on at the start means you actually get a seat! It is also just a 10/15 minute walk from the port where you can get a ferry to Capri and Ischia as well as other places.
The apartment itself was very clean and spacious, very up to date, the bed was comfortable and it has everything you could need, with excellent air con for the summer months. We stayed in August and weren't hot in the apartment at all.
