Hara's House 3 is in an amazing location in Santorini. The view is perfect (specially by the pool). There are also lots of shops and restaurants close by. The main town is not far either but recommend to get a taxi if not too keen on walking. Check in and out was easy and quick. We also had transport organised from and to the port (€25 for three of us each way).
The house itself is very clean, comfortable and offering all essential needs. Wifi works well (better in the house than in the pool area tough).
I would definitely recommend it.
