Vincenzo's apartment is ideally placed to explore the centre of Palermo. Dipending on how much street food you have eaten, the vast majority of attractions in the city are 10-30 minutes walk from the apartment (for example Teatro Massimo was typically 20 minutes away). For things further away such as Mondello or Cefalù, the apartment is 10 minutes from Palermo Centrale, and there are plenty of busses to get around the rest of the city.
There are plenty of very nice and reasonably priced restaurants within less than 5 minutes walk of the apartment.
The apartment is all air conditioned, everything was clean and working, and Vincenzo immediately made me feel at home, and was happy to give me details or recommendations for public transport, attractions etc. This room also had it's own little shower/wet room, which at least for me made the morning a lot more convenient.
All in all I would recommend Vincenzo's apartment to anyone who wants a convenient, well priced, friendly room from which to explore Palermo.
