This is a great place for cat and animal lovers. Very friendly & helpful staff, and they can help you to save time and money by organizing your transport: Let them organize your taxi coming and going, and don't take the shuttle from the ferry....
It was well-located for my simple overnight to access the airport, only 10 minutes away.
It is just a couple of minutes from the beach, restaurants, shops.
Santorini in the summer is insane: Never again. Had not been there in 40 years (pre-airport and pre-cruise-ships...) Kamari Beach offers ample good restaurants and venues to drop into, yet is probably less stressful than other areas. Certainly the traffic congestion was nothing like what I saw in Fira and around the Caldera (and I was there on a day without cruise ships!).
It was high season and last minute and still this accommodation felt overpriced. Everything I used worked: wi-fi, AC, hot water ( there is also a small cooking corner). There was a small balcony w/table and chairs on both sides of the room.
It is bare-bones functional, have no illusions of design or charm.
It was a 4-bed room, I was alone, and can't conceive of having 3 additional people trying to navigate that space.
