Raki Cave was a fantastic place to stay. It is furnished simply but stylishly, and the bed was extremely comfortable. Raki Cave was very clean, and Fotis even came by daily with clean towels and to do a quick pickup of the place while we were out. I've never had such service with an AirBNB.
Raki Cave is about a 10 minute walk from the middle of Fira, but it's an easy walk. It is removed enough that it's a very quiet place to sleep. It's easy to get where you need to go.
Fotis was an excellent host. Check in was easy, he met us upon arrival and helped carry luggage and walked us to our room. He gave us a quick tour of Fira, helping us to get oriented quickly. Fotis also helped arrange transportation to and from Raki Cave, which was nice as we don't speak Greek.
The whole experience was a 5 star event. We would recommend it to anyone looking for a central place to stay in Fira.
