The view from the apartment/balcony is classic breath-taking Santorini. Theo's hospitality is next-level outstanding. The apartment itself is rather basic and probably a little tight even for 2 (sleeps 2 but space for luggage is limited), but has everything you need. Steps are no joke - definitely use the porter for luggage, and even then take care with walking outside and inside!
Overall reasonable value in Oia, especially if you will be out during the day.
