My friend and I stayed here for 2 nights in the first week of August.
We felt the accommodation was a real tribute to Santorini. We really enjoyed the layout having all the rooms come off the courtyard, but could see how this could be an issue for families with young children (none of the rooms link internally so essentially the courtyard is the hallway).
It has everything you need for a short break including air conditioning in both bedrooms/living room, functioning kitchen, hairdryers, bath and beach towels.
Tourists do overlook the courtyard and often stop for photos of the view (this happens over every courtyard in Oía). If you have an issue with this, ensure you take clothes into the bathroom when showering - you don't want to be running into the room in just your towel with a bunch of people taking photos above.
The location is perfect, it's centrally located but far enough away from sunset point to dodge the big crowds of people. The view is amazing, perfect views of the caldera. You certainly won't be disappointed staying here.
We arrived by ferry and opted for the private transfer from the ferry, this cost 30 Euro. We later discovered that the local buses are super easy to use and cost 4.10 each person. You just need to transfer buses in Thira which is at the same bus stop and is super easy.
We would highly recommend staying here.
