Great stay, the apartment is huge! Splendid space with stable internet (more than enough for remote working), a fully functional kitchen and great bathroom. (hot water didn't run out!)
Heating was effective and easy to configure using the touchpad beside the bed, and we had everything we needed for comfort.
The double sofa-bed isn't the best sleeping experience ever - it's a bit creaky and too soft, but it suffices. There's also an extra single bed which has a great mattress. Not a deal-breaker, but it's good to be aware of it.
Eugenio was one of the nicest hosts in recent memory, offering recommendations for restaurants, supermarkets, anything! A map was provided upon arrival with points of interest, and that helped a lot.
The apartment is in a prime spot, with many great places and tourist spots within walking distance.
He also quickly answered any of our doubts, even pointing us to a place to buy packing tape.
Overall, one of the nicest experiences we had with Airbnb. Highly recommended if you're staying a while in Palermo!
