Not much more to add.
The bad: Owners not too personable or friendly, mattress hard as a rock, shower small.

The good: All of this is easily overlooked with the wonderful location, view and room size. Reasonably clean. Our room had a small kitchen which was appropriate for making coffee, etc. in the morning with glasses, dishes, pans, etc. Could watch the sunset from the pool area, although arrive early, all of the other guests have the same thought.
Pools (2 of them) were beautiful and clean, but too cold for us to go in. Parking was pretty easy a short walk away, not sure if it would be as easy to find in high season.

Very Good value.

The location of this hotel is everything. Although on the outside edge of town it is situated on a hillside offering a manificent view of the caldera. And at a reasonable price. We had a suite with two bedrooms and cooking facilities which we found excellent. There was a well maintained swimming pool and sitting area below our unit. The walk into town was some distance but not unreasonable and the views from the walkway were spectacular.

Myself and my husband (early 30’s) stayed in Olympic Villas for 2 nights recently. We got a great bargain but did not have a view looking over the cliff side of Oia but we didn’t mind as you can easily stroll out to the pool and admire the scenery.

The Villas are on the way into Oia from Fira, there is a rental place across the road from which we hired a quad to explore the island. Oia is definitely the best place to stay in the island. The capital Fira is nice but not a patch on Oia. The owners of Olympic are a young family and are not super friendly but were always helpful when we needed them so that was perfect. The room was clean but as per usual for everywhere we stayed there was a pretty standard wooden bed and a shower that does not hang up and has a shower curtain (we found this everywhere in Greece).

The town of Oia is around an 8/10 minute walk away along a lovely pathway that looks over the fabulous cave houses and swimming pools of the expensive hotels. Each night we walked down to the end of the island got some take away beers from the supermarket and sat on the walls to watch the sunset with hundreds of other people. The views are simply spectacular and the atmosphere is great. We found the prices in Santorini closer to Irish prices (dinner for 2 with wine €80/90) so we were glad we didn’t spend loads on accommodation. I would definitely recommend this hotel to anyone, the location is perfect and it’s great value (we booked through a travel agent book-santorini-hotels.com)

We stayed 6 days. Oia is definitely best place on Santorini and the villas close to the village, but far enough away to avoid all the crowds.
The pools were fantastic and the views amazing. The rooms were great - we had a superior apartment which was worth the extra as we were in a smaller apartment on the first day.
The owner's mother is really lovely and made us so welcome on arrival (at 7am) and let us put our toddler to bed in one of the smaller apartments as our's wasn't ready. She could not have been nicer.

Would definitely stay there again. Oia is gorgeous and much nicer than Fira. We did the sailing trip recommended in the welcome info - day trip to volcano, swim and lunch on a small island - brilliant and fine with a very active 20 month old. There is a little playground in Oia village which was great for toddler too. Our sturdy maclaren buggy was fine on the steps etc of the village, but when we went to see the sunset we just carried/walked Will due to the crowds. Resturants very toddler friendly and welcoming.

There are a couple of good stores - directly across the road and down the path also - 'perivolas'. Easy to buy fruit, milk, juice, beer, pasta and sauces etc. Opposite perivolas there is an excellent pub (tavern) with delicious and well priced food and drink and they also do takeaway food - so can bring it back to the villas and eat with caldera view. Magic.
