Maria Theresa's place is at the edge of the town about 10 minutes from the Square. Our room was big and bright and we had our own big modern bathroom. We made tea in our room and left the milk in her fridge. Lots of nice restaurants nearby and her daughter Eisillia was so good and kind and gave us recommendations. There's a good gelateria and pastry café across the street.
For those new to Airbnb, you just have to pay the amount on the original listing. You do not have to pay extras your host may ask for later on.
