We loved our stay at the Ersi villas cave house. Elias gave us great recommendations for restaurants and activities, such as the early morning walk to Oia. The villa is in an excellent location, about 5-10 min walk from Fira and 3-5 min walk from Firostefani which has excellent restaurants- we highly recommend Aktaion or Onar for dinner, and Why Not souvlaki for a gyros. As it is located outside of Fira, it is a much more relaxed atmosphere. The pool was excellent as it gets quite hot during the day. Highly recommend staying here! Note: if you are 6 foot or taller I would book a different room at the villas as you may not fit in the bed.
