Eleni was an excellent host. She was responsive, picked us up from the airport, and gave us useful information about the island. It was cool to stay in a cave apartment, and I definitely recommend staying in/near oia rather than Fira if you are coming for a short visit.
What I did not like about the apartment however were the following: it was difficult to shower with the set up of the bathroom, we found a lot of big scary bugs late at night (which, again, I am not sure you can truly avoid in a place like this), and the location of the apartment is a little bit of a ways to oia. Additionally, because you cannot drive down the nearby streets, you have to take your bags on a journey up and down a lot of steps that took about 10 minutes. I normally would not mind this, and while I did definitely appreciate Eleni picking us up for the airport, I thought that since she charged us 40 euro for that service that there should have been an easier way to take our bags in.
Overall I loved Eleni as a host but I do not know if I would recommend staying in this particular apartment.
