This is a good value for the island, which is extremely expensive. That said, it's run more like a hotel and lacked some of the connection/charm of an airbnb experience where the host lives in the space itself.
The area you're in is very sweet and a little away from the central Oia strip, which I preferred. There's a brand new restaurant (Lefkeys) that is AMAZING and a few steps away.
The room itself is cozy but comfortable, equipped with a mini fridge and small kitchenette. We had some cleanliness concerns, however, the ironing board had sticky black grease on it that got on our clothes and the bathroom had a terrible ant problem.
Getting to the hotel from the airport is difficult but luckily Margarita will provide support getting to and from (the buses take a REALLY long time and don't run on schedule). It's not an easy room to get to/from the parking lot, so she also asks someone to help us with our bags, which is useful. But the 'taxi' will be a more like a van service, so you may be riding with others either on your way there or back. This was fine but we weren't prepared for this and had to wait some time when we arrived at the airport because the van was picking up a few people (not everyone was staying at our hotel) and each of us owed the 30 euro..
All this notwithstanding, it was a generally good stay and if you're looking to have a cost efficient stay on Santorini, I really recommend this place.
