We spent a week at Grigoris' place at the end of September and thoroughly enjoyed our stay. The apartment is clean, spacious and has great amenities. The views really are stunning and you have your own private space to sunbathe and relax by the splash pool, we barely left the space all week it was that peaceful. Make sure you have transport when staying here as it is pretty remote and out of the way if you want to get to Oia (20 mins drive) or Fira (10 mins drive). We used a rental company called Marks Bikes who delivered a quad to us for a great price for the week. Our host, Costas, was very attentive and communicated perfectly with us on Whatsapp for any questions we had after he had checked us in. There was an issue with the shower and electrics during our stay which was resolved pretty swiftly.
A few of things to note are; there's another villa below the apartment, which you overlook onto their patio area from the balcony, when people are staying there you feel a bit like you're imposing on their space, this might not bother some people. The shower needs improving as we found it to be weak then fluctuating hot/cold and it was a shame that the bath tap does not work as it would be nice to relax in after a long day of travelling. The pool was great but only got cleaned once during our stay, others mentioned this was daily, which wasn't the case, so be prepared to clean this daily yourself as it gets full of bugs as there's no net to cover it at night. Sometimes people just walk in through the ungated side entrance which felt a bit unprivate at times, so be aware of cleaners coming in. Food recommendations would be, for breakfast check out Galini (amazing food), for lunch/dinner; Rare Meat Restaurant (great steak), Ginger Sushi Lounge (expensive but good) and To Honaki for a cheap eat. Cheapest supermarket nearby is Supermarket Nissi we found.
