Great stay with Helen. The hotel has a great pool, that I wish we could have used but it was very chilly in Santorini due to the Medicane. We liked that the room was cleaned and bed made every day. The room has a good view of the pool, and is stocked with basic limited kitchen supplies. There is a grocery nearby. You have to drink bottled water (much to my eco friendly demise) as Santorini has no fresh water.
Helen offered lots of local tips and was available if we needed anything. There is a great laundry just a few feet up the road, it only cost 8 euros to wash and dry. It is connected to an amazing gyro place called Grill House! Best gyros and gyro plates we ever had! The creatan bakery farther up the road was delicious as well.
The location is about 25 minutes walk to Fira, which we didnt mind because it was cooler than expected..but a ATV would be helpful in hotter weather. You 100% need an international driver's license if you're from the USA, or you wont be rented to in Greece.
The buses from the fira terminal to oia and back are cheap (1,80€ per person). We also recommend the hike to oia from Fira for a scenic view.
Thanks Helen!
