We visited Palermo for a couple of days and chose to stay at Toti's in the first place mainly because it looked central. It was a great decision and not only because it is de facto right in the heart of the historical part of Palermo, but also for Toti himself.
Toti is a superhost that did all he could to accomodate us to the best he could. He was available for any service or advice we may need, provided us with a list of great restaurant and even booked the famous Bisso for us in 5min ! (Ok it is not guaranteed as it is very busy but still, it was great to see how well he is connected to the locals).
The place was spot on and and spotless, very well equiped, nothing I could think of to be fair. And it is very spacious too, the bedrooms are huge (probably 20 and 25m2).
If we ever have the chance to come back to Palermo, we would come back to Toti's, a gentlemen and a superhost.
