Everything about the apartment was great. Although in the heart of La Kalsa, the apartment is in a very quiet location. It's just a few metres away from shops, bars, restaurants and some of Palermo's key places to visit. (Toti and Caterina left a very useful "guide" to their favourite local places. They also were very helpful before and during our visit, replying quickly to all our queries.)
The apartment itself is perfect. There's ample space for two people and it features everything that a visitor could possibly need. Best of all is the large terrace, which overlooks an old ruin inhabited by various cats.
We would love to return and highly recommend the apartment.
