My friend and I booked a tour with Above 90 about a month before our trip to Italy. It was going to be our most expensive tour of the trip (a "splurge" if you will!) and we were very much looking forward to it. Silvio was great with his email communications and was very accommodating to make a tour that would meet our expectations.
The morning before our tasting, Silvio emailed us to confirm and we quickly responded with our confirmation. When we returned to our hotel from a day of sightseeing and checked our email to find that our tour had been cancelled. Silvio cited car troubles.
While I totally understand that the unexpected can happen, I was very disappointed that we got such short notice for our cancellation. We asked if he could rent a car or suggest other options. He gave a few suggestions but it was too late to book them.
It was very disappointing to leave Tuscany with no wine tasting experience.
I've heard nothing but good things about his tours so I still encourage you to book but I also encourage you to plan a backup option!
