Can't say enough good things about the apartment. Best part was the host, who was really friendly and accommodating and everything was wonderful in that respect. It's a secluded location which is kind of nice in its own way... The apartment is definitely quite a distance from Oia in terms of walking - walking to it is not very realistic but still, it wasn't a problem - our host ordered atv 's for us and that was very useful anyways, since you'd need one to explore the island fully.
The apartments themselves are very charming and beautiful and everything is well maintained.
In short, we loved our stay here and would highly recommend it for anyone coming to Santorini!
