Dennis’s place is an amazing stay in Oia. Its very centrally located, right on the main street in Oia, with very few stairs that take you down from the main street to the house. Also, the bus stop, pick-ups for tours n cabs were within 5 mins walking distance. The view of the caldera is spectacular from the front area of the house. The bakery/restaurant next door was very convenient too, as we had our breakfasts there. The TV at his place had extensive collection of english movies and TV series that you could browse and watch when inside.
Dennis was very helpful in arranging very convenient transportation for us from the port to the place and went out of the way to help us during our return transport to the airport. Also, Danae and Dennis helped book a very good and cheap boat tour for us as well.
I would highly recommend his place to anyone looking to stay in Oia, especially 4-5 people as his place has 2 good bedrooms.
