Nicoletta's house is amazing. It has the most breathtaking views of the caldera from your own private balcony. It is located near to the old castle where people come to take photos of the sunset. I dont think you could beat this locstion. It is nesr to alll the shops and restaurants and also the bus ststion.
Nicoletta's daughters met us on arrival and spent time informing us about things to do in Santorini
Would definitely recommend this air bnb. It had everything you needed
