We stayed here for 8 nights, and would definitely stay again.
The house itself was modern, spotless, well equipped, and was everything we expected and more. The absolute best thing about this accommodation is the location...it is literally 1 minute walk from the main street in Oia. You have to walk up some pretty steep steps to get from the accommodation to the main town, but it was easily manageable and nothing to be concerned about if you don't have any mobility issues...we just looked at it as an opportunity to burn off a few calories after all the lovely food & drink!
The best point to view the sunset is only a five minute walk away, but the view from the accommodation itself is stunning, and fantastic to see when you open your window/door first thing every morning. The private seating area at the front of the house (with chairs, table and sun lounger) was a great location to sit in the early evening.
Maria (and Ef) were able to organise a transfer from and to the airport, including porter, which made the whole process so easy, particularly as there is no vehicle access to the property and it would be quite difficult to find your way there otherwise.
The accommodation itself was spotless, cleaned daily and had everything we needed, including fridge, hairdryer, fresh towels every other day, cooking utensils etc...although with so many fantastic restaurants nearby, we didn't feel the need to cook in the apartment.
Maria's associate Ef met us at the accommodation and was super friendly and provided lots of great information regarding things to do and see during our stay, but without being pushy. He was also able to organise anything we needed and really made things easy for us.
If we return to Oia, we would book here again without a moments hesitation...we had a great week, and the location of this accommodation is the real star!
