My stay was quite different from the reviews I read and perhaps it is because they are using a third party company or some other sort of co-host to run the place. This practice is allowed within Airbnb regulations, including for Superhosts. We were met by a young man who was obviously new to checking someone in, charged us a small cash tax not disclosed on Airbnb and when I asked about it, he said it was a new business and he didn't know the rules.
The power went out 4-5 times the first evening. It took awhile to figure out how much electricity could be used before the circuit breaker shut off again, which meant running down and up few flights. I ended up taking a shower in the dark with the heaters off in the end because didn't want it going off on me again while showering. We were shown where the circuit breaker switch upon check in so obviously this happens often - we just didn't realize how much until using trial and error. After the trip, I was emailed asking how the stay was and I let them know that the power went out. The only reply I got was that no one ever complained about it before.
There was a bigger bed which had a very soft mattress. There were three single beds. One had a hard spring running up the middle and the other two were pretty soft but okay.
Good things about the place included the espresso maker, milk, juice and water were available, and there were breads, crackers and cereals provided. The location is central and within close walking distance to the sights of Palermo.
Overall, the stay wasn't bad and I think the frustration with electrical problem could have been avoided with some simple instructions from the host. Hopefully, Giacomo will come back and provide his personal touch to the place, which sounds like it counted for a lot.
