Margherita's place is centrally located, just a few blocks away from the bus and train terminal in Palermo. If you need to venture to the rest of Sicily, I highly recommend staying at her place for the easy access to transportation. This also applies to shuttles and shared taxis that go to the airport. I had a morning flight the next day, and it was super easy to get to the airport from her place hauling all of my luggage.
The apartment is also at the beginning of market Ballaro, which is a great, extensive local market.
Basically, everything you need is just a few blocks away and what Palermo has to offer is 20-25 minutes away from the apartment by walking.
The place itself was great! The bedroom was comfy and lovely. The shower was fantastic, and I really love the living room where one can have breakfast in the morning or just chill in the afternoons. The overall vibe reminded me of a hostal, but without the craziness and parties that come with having so many hosts.
Margherita was also kind enough to give me tips and recommendations on what to do and where the locals eat. She would help you out if you want to, but also give you your privacy if that is more of your style.
