Vivi was the perfect host. She arranged for us to get to and from the airport, brought us homemade treats, and checked in on us half way through the week to make sure things were going OK. The house is very cute. One thing to note is that it can get noisy at night -- the narrow street that runs just outside the entrance is popular with motorbikes and pedestrians, and there's nothing to block the noise. But other than that the location is ideal: close to downtown Fira and great views of the caldera, the main street, and a great little food market that I highly recommend visiting.
