Ultimately, the location of La Mer Cave was great. It provided an amazing view of the caldera and allowed for my wife and I to stay in a cave house in Oia, which is a unique and once in a lifetime experience for most. That being said, we never saw our hosts and they were a bit short over messaging, though they did provide a porter service which was appreciated. We have had multiple experiences on Airbnb, and this was our most expensive rental which I guess made our expectations higher. The cave was as shown in the photos, though a bit less tidy (e.g. cleaning service left vacuums out and mops drying on the patio and cords from various appliances and lamps were not shown in photos). Also, there was a single bottle of water provided, which we appreciated, though zero toiletries and no coffee or breakfast supplies. Also, one small bed was made, but but the rest were not though sheets were provided. This may have been because we were a single couple. Also, the towels may have been the roughest I have ever used. I don't mean to complain and nick-pick, but considering the price and when compared to some of the amazing and welcoming experiences we have had on Airbnb in the past, it was a bit of a let down. Again, the location was excellent, the cave house was clean and very similar to the photos provided, and the porter service was very helpful. I would recommend. Oia is competitive and expensive, but I would be aware for your own expectations.
