We stayed at Danai House for 2 nights. The pictures really don't do it justice, it's beautiful yet very authentic and you don't get that 'fake' vibe that you could get in some places in Santorini.
Oia is just amazing, yes very touristy, but still absolutely worth it.
Communication was easy and smooth.
Maria organized for someone to collect us at the bus station and to take us to the house.
Following that Maria came and spent a good 15 minutes with us and a map giving us excellent tips on what to do in the following days.
It's all absolutely perfect, I would definitely recommend to anyone and hope I get to go back myself sometime, one time in Oia is really not enough in a lifetime :)
