The Boat Builder's House is in a great location, close by to the major sights of Oia and the bus terminal. Manolis helped arrange a pickup for us from the ferry station and back to the airport (€40/each way) and personally met us nearby the bus terminal to bring us to the apartment. He gave us some restaurant recommendations, including one where his friends' band was playing that night, right down the alleyway. There's a wonderful balcony where we sat in the evening and enjoyed the breezy night air. All the windows have shutters so we were able to get a good night's sleep (some bright lights nearby). You may have a cat visitor or two from the family that lives across the alleyway! I'd highly recommend staying with them!
We ended up hiking the path to Fira (3 hrs one way) for a sunset reservation at a restaurant there, then taking the bus back to Oia (€2/person) one evening. We also went on a daytime snorkeling/sailing trip with Sunset Oia that was a fantastic trip to a few spots around the island (5hrs, €107/person, https://bit.ly/2lAmz2N).
