The Altea Apartment is very modern and clean. Helen made sure to keep it very tidy during our stay in Santorini. It is very centrally located and within walking distance to shops, market, square, nightlife, etc. You can even walk to Forestifani (15 minute walk). I rented an ATV to explore the island, but if you only want to do Oia for the sunset, you can catch a bus if you don't want to drive an ATV. The Altea apartment team was very helpful and even booked a Caldera yacht excursion that was fantastic on a beautiful Catamaran. Transfers were arranged and all went well. Fantastic stay and would recommend.
