We had a nice stay at Vivi's place. It was clean and we found everything we needed. It's well located in Fira, close to the bus station that allows you to go to all sites on the island. Besides, it is near grocery stores, restaurants, the post office, pharmacy, etc... Everything is at a few minute walk.
It is located near The Caldera with a stunning view on the sea and the cliff.
We communicated well with Vivi before and throughout our stay.
I recommend her place.
