Spent two nights at Konstantinos place with my sister, we had a lovely time! The place has everything you may need, it's very clean and modern. We were given a welcome pack of breakfast items, fruit and Greek alcohol which was a nice addition! The location was a lot closer to Oia than we expected, only a 10 minute walk at most! Very close to the bus stop to travel to Fira and other parts of the island (quite frequent and very cheap). The villa, however, is located at the bottom of a really steep hill which may be an issue for people with mobility problems. So maybe rent a car or get a taxi if this may be an issue for you! Cute little Greek restaurant that had traditional life music at the top of the hill which you should try! Overall, loved the place, very reasonable in comparison to other places in Oia and would definitely recommend :)
