Susana and Màximo were very nice and helpful. As we arrived before the check in time they very kindly let us in early. They also supplied a lot of extras like coffee, a card for the subway and even some welcome-beers!
The apartment is really central in Palermo and close to a little shop where you can buy necessities like water, milk, fruit etc. It is also close to a lot of cafés, bars and restaurants.
I would 100% recommend staying at this apartment.
