We had a great time in Santorini and really enjoyed Christina's place. The apartment is pretty and it is in a quiet neighborhood that is an easy five-minute walk to the town centre (where the bus station is) and to the edge of the caldera. There are also several mini markets within a three-minute walk, which made it easy to keep the refrigerator stocked.
Christina arranged for a transfer from the port to the apartment, which made things much easier when we arrived after our long journey.
Christina was also very responsive - quick resplies to our texts and Airbnb messages. When we had a minor problem with our air conditioning Christina sent someone out promptly and it was fixed.
We're also really glad we stayed in Fira. It has lots of narrow, winding walkways and streets, a mix of quiet residential areas, commercial areas, and restaurants, and its central location on the island makes it easy to get to Akrotiri in the South and Oia in the north for day trips.
