I have been using Airbnb over the past few years and Andrea is one of the greatest hosts I had so far.
The place was incredible, worth every penny. 5 min walk to Fira square, local buss stop. Less than 10 min to supermarket. Balcony has an amazing view over caldera.
Breakfast was great with multiple options. She also help us with private tour over the whole island and recommendation on local restaurants.
