I ended up staying at Stavros Villas 2x. Both times were quite enjoyable. Eva and her sister Emma are very welcoming and make one feel at home right away. They were quite helpful as well. Their father picked me up at and drove me to the airport and port and arranged a scooter. The accommodations are spotless, comfortable & quite large. The place is a bit outside of the main town Fira but so are most other places and that's also maybe another positive point as one is away from the tourist mass. However, there are a few restaurants and mini markets close by and within walking distance. Its location however is quiet and has a great view from the eastern side of the island. If you get up early you get a great sunrise. All in all quite enjoyable and good prices for Santorini. I can recommend it.
