This hotel is absolutely fantastic! This being our first trip to Santorini, I researched A LOT of hotels and places there, and decided on this one simply because we wanted to be away from the tourist mobs in Oia (an excellent choice - it's BUSY there!) and it looked nice. When we arrived Vassilis greeted us warmly, gave us some tips for the island, and showed us to a beautiful, spotlessly clean room. It had a great private balcony with stunning views of the caldera. (note: the sunset views are just as good from there as anywhere else on the island!). The hospitality, service, facilitates, and location were all fantastic and we would definitely stay here again.
Vassilis helped us book an ATV for our stay (about 30 euros/day) and I would HIGHLY recommend doing this. You can see some great parts of all of the island and it's really easy to get around, park, drive, etc.
A great place - you absolutely will not regret staying here.
