Just spent 7 nites with Nicoletta at the Beach House. This is a wonderful property and Nicoletta and Alexandra were very helpful both before we left for Greece and once we arrived. The Armeni Beach house is very clean and in great shape. If you are looking for a place to decompress you can't do better! The water is feet away, a nice breeze makes it comfortable all day long. Usually when we travel it is too cool for my wife and too hot for me. we were both comfortable, we never had turn on the AC. The house is set up great for cross ventilation. There are about 12 full time people in Armeni it is quiet and very relaxed pace.
The house has everything you need; we shopped for groceries on our way in (Nicoletta recommended a great local market). We prepared our own breakfast every morning and we ate next door at the Armeni Restaurant for many lunches and all but one diner. The food is unbelievable and the staff is even better; Niko's, Yanis and Lambros became family and they truly welcomed us to the neighborhood.
We used the sea kayak's several times, If you are a scuba diver Atlantis Oia dive Center is next door. We did (2) Two-day dives with them. The equipment is in good shape; if you plan to dive with them and have a dive computer bring it along they don't have those available. Captain Alex who run's the boat was very accommodating and always available (boat ride is 5 min). We rented a car and we parked it on the side of the road heading to Ammoudi Bay. If you aren't really comfortable with a manual transmission I would suggest using car service; Nicoletta and Alex can help you with this. When we arrived Alexandra met us at Ammoudi Bay and showed us everything we needed to know about the house; the internet is decent at 15-20 Meg.
One day we did hike up the 284 stairs and spent the day Oia and stayed until after sunset which is a MUST do. we took the stairs back down to Ammoudi Bay (becareful donkey's are used on this road and lots of "road apples" to avoid). The only downside to Armeni Beach for us is we had to push ourselves to leave and explore the rest of Santorini which has so much to offer. Visiting Santorini was a dream of my wife's for years and it was fully realized. We will be coming back and will definitely return to Armeni Beach.
If you are into comfort, chilling out and don't mind taking a few extra steps to experience local life you will not do better. As we traveled the island we couldn't find much in the way of beach front accommodation with a full view of the Caldera; this is truly and unique experiance.
