We stayed at the villa for 5 nights in early June. Aris was very accommodating and helpful with lots of information about places to eat and things to do in Santorini.
The location of the villa was excellent. Taking the caldera path to Oia was a 5-10!min scenic walk to the pedestrian street of Oia (where the grocery store was btw). The villa is close to the busy part of Oia, but still away enough to be able to relax at your pool without having to hear the traffic and the thousands of people visiting Oia for the sunset every day.
The pool is actually large (is not a plunge pool), and you can enjoy the caldera from the back terrace of the villa and also the famous Oia sunset from the front porch of the villa. The neighboring villas on each side are very close, but the tenants were quite and friendly and the overall setup was very quite and relaxing. We were presently surprised to realize that we only had neighbors on each side of the villa and not above and below (which is typical for Oia, since everything is packed).
The villa itself was a little dated (as others have mentioned) but that should be expected for the advertised price for an accommodation at that popular location. The rooms were large which is unusual for a rental in such a popular vacation destination.
I would recommend this villa to anyone looking for a quite place to relax, reasonably priced that is one of the most popular destinations in the world.
