The 3 Caves Suite was a phenomenal stay for us during our Santorini wedding! The views are so outstanding you will feel like you're in a dream that you never want to wake up from while sipping Santorini wine in the hot tub at night. If you're planning on a trip to Oia (which you definitely should if you are staying in Santorini) then you will not be disappointed. We never met the hosts who have 19 properties to manage, but the concierge Mary was exceptional and very responsive on Whatsapp (make sure to download the app if you are from the US to make communication easier during your stay). We had to rebook our stay twice due to Covid and the hosts were wonderful about making the changes. The meetup at the post office was a bit chaotic as it's not really clear where exactly the post office is (our driver just dropped us off in the general area) and there are a lot of people around in the afternoons, but we did find her after a few minutes (maybe just telling her what we were wearing would have made it easier in hindsight). Having breakfast delivered each day was really nice and I especially loved the chocolate waffles and delicious jams with greek yogurt. The place is really tucked away and one of the more private villas as it's at the end of a footpath so you won't get people walking directly by (unless they get lost, which did happen once). It's nice and cool in the cave which is very welcome after a day of exploring the streets of Oia in the hot sun. You do need to remember to turn the hot water on 10-20 minutes before showering and turn it off afterwards, which we did forget a few times but luckily it didn't take long for the water to get hot. The hair dryer did go out every time I used it, so I always had to unplug/turn the switch on the wall in order to finish drying my hair, which was a tiny bit annoying but not really a big deal. Wifi was great and reliable.
We got married in Imerovigli during our stay and had a ton of space to spread out in the villa which was great for getting ready prior to our wedding. I was able to hang my dress (with a long train) up high on a sturdy bar in the bedroom for steaming out of view of my fiance and have a hair stylist and makeup artist come with plenty of room for them to spread their things out as well. Since we had the porter bring our luggage for us it was no problem for us to find the place, but my wedding hairstylist and makeup artist had a hard time finding it because there's no addresses in Oia (only names of villas) and google takes you down a weird path to get there which was on the opposite end of the main path we took with the porter. They were a bit frazzled at having not been able to easily find the place but it turned out okay in the end. We also arrived in the afternoon and were hot sweaty messes by the time we made it down all the cobblestone steps (even with the porter carrying our heavy luggage), so much so that I was really worried about having to climb back uphill on my wedding day in my dress and having my makeup melt off my face. It turned out not to be a problem at all because we took our time and I wore comfy sandals and carried my wedding heels until I got to the venue. Also we had a sunset wedding so at 6:30pm when we left the villa, the path was mostly shaded. It's roughly a 5-7 minute walk up to the main pathway through the crowds to the actual street where our car picked us up, but we gave ourselves about 20 minutes so we could take our time and take a few selfies along the way.
There are a few things that would take this place from exceptional to out of this world: 1. the jacuzzi was warm but if just a few degrees hotter would have been perfect, and 2. the comfort level of the bed was a 7/10 for both of us and blankets were kind of thin. It seemed like the mattress had been well used and it was probably the least comfortable bed out of the four places we stayed in Greece, though not uncomfortable.
There also were no washcloths for the face even when requested so if you're someone who uses them regularly be sure to bring your own. It also gets slippery on the concrete floor in the bathroom when the water inevitably will spill out of the shower (which we found to be the case in all of Greece bathrooms), so be careful to dry the floor thoroughly afterwards.
All in all we had such a wonderful stay here and would come back in a heartbeat. We would definitely recommend this villa for a honeymoon or wedding stay. You won't regret it!
