Due to COVID and our preference for quiet and privacy, we intentionally chose to stay at a property not in Fira or Oia. I am so glad we did! Downtown Kamari is small and close by. We appreciated that it was quiet at night--which may not be your preference--and the property didn't feel crowded or exposed, which so many places in Oia looked to us. (If you don't have a vehicle rented, this hotel may not be ideal for you because it is not as centrally located as others.)
The service at this quiet, beautiful property was fantastic and took our wonderful experience to the next level. Each staff member I encountered, including the general manager who called me shortly after my arrival, were extremely helpful and prompt with their assistance: people helped us book local restaurant reservations, gave us tips for visiting Fira and Oia, have laundry done, and more.
The breakfast was also excellent. Just be aware that you need to select which breakfast items you want by filling out a form and giving it to the front desk person before the next morning.
And if you book a room with a hot tub, you'll need to ask the front desk to turn up the heat at least an hour (it took about two hours for us) before you'd like to use it. This may feel like a nuisance to some, but it kept the bathroom from being too hot and steamy during the rest of the stay. If you're an American and used to scalding hot tubs, be aware that these hot tubs will not be as hot as what you're used to.
