The place we rented was great!
There was miscommunication with the driver picking us up, so let them know you need to be picked up not just your arrival time. Also they will take you to check in with the office a few minutes away from the rental first.

Having the pool close and AC helped tremendously. Bianca was great! Serving breakfast every morning and help with other questions. The beach is only a 5-10 minute walk and lots of shops and restaurants there.
There is 2 close markets as well to get water, drinks and snacks. The further (BIG Discount Market) one will actually shuttle you back to your place.

The beach was great you can either rent an umbrella for 10euros for the day or purchase drinks/food. Also there is a water taxi (just ask anyone there where to go) that will take you over to Kamari Beach.

I highly recommend doing the Greek Food and Wine Tasting with Santorini Wine Tour. We did it the first night we arrived which was nice to not have to worry about dinner and George was great!!
