We had a great stay! The apartment is nice and confortable and Jim was very helpul and always prompt in responding to our requests. He also left us a user manual of the apartment with all the information needed.
The apartment is very bright with a lot of light coming in, a bit hot in the summer but all the rooms have air conditioning, that was very appreciated! It is located not in the lively Palermo but it's very close to the subway station, just 5 minutes walking.
The only issue is the noise coming from the street, where there's usually a lot of traffic so if you are a light sleepers it's better to have ear plugs with you.
