We are a family of 5 (kid15,12,9) and have just spent 4 nights at Oia Sunset Apartments. The apartments are in a great location in Oia, walking distance to all the facilities in the town as well as the amazing view of the caldera. Mr Panos and Stavros are great hosts and they can organise car hire, boat tours etc,as well as suggesting places to visit around the island.
The pool is great and a good idea if staying in Oia. Would definitely recommend the apartments especially with a family.
