I have been using Airbnb for 4 years now. I must say that Andrea is by far the best host I have come across to date. She was proactive in communicating, she responded virtually instantly and anything we discussed and agreed upon was done; there was no need for follow up queries by me.
I still wish I was in Palermo right now and Andrea's apartment is a great base to explore this neighbourhood, Don Julio's is a few blocks away and Plaza Serrano is in walking distance. The underground rail network has a stop two blocks away.
I couldn't recommend Andrea and this apartment more to anyone; enjoy!!
