It's hard to remain objective when you feel so confortable with the hosts. I think that's 99% of a good airbnb, even more when looking for private rooms.
We had a fantastic stay. True to the map, it can be a little far away if you are one of those who like to come back to your place during the day, but if you're smart to organize yourself a good day trip bag, you won't have any problem.
You need to be careful that there are some better ways of reaching the place by public transport than others, and plan a careful timetable to organize your visits, since you will need this extra time to reach the place.
We didn't have so much time to share with Antonio because of his work, but we had very nice talks with Robert who makes you feel at home, with patience and dedication to explain everything you need concerning the house and tours.
