This is just the truth, folks. Sitting in a U.S. airport ready to board our plane to Italy, I got a message that our rental had been double booked and was asked to cancel my reservation. This was 48 hours before we were to be in Bologna. Alessandro is very good at apologizing and telling us we were getting a deal on a different apartment that rented for more, (we did NOT pay the difference) but it wasn't what we had wanted or booked a long time ago. The only positive was that the location of the second apartment. It was a voyeur's dream that had a glass wall in the bedroom, no privacy, with one bathroom (we had booked a unit with two) in which the toilet was broken and the shower, however careful one was, flooded the bathroom and made the tiles very slippery. Most of the towels went to mopping up the floor. I don't know how his units can be double booked, but just be aware that your reservation may not be honored.
