We stayed over one month and can say Guille's place is very well located within walking distance from many restaurants and very well connected with several bus lines just 1-2 blocks away from the flat. The place is exactly as the pictures shown and Guille was very helpful whenever we needed anything from check-in/out to sorting cleaning whilst we were in the apartment.
Would definitely recommend it to someone looking to stay close to all the great restaurants and venues in Palermo, but also in an area that's a bit more calm down than being in the middle of Palermo Soho.
