We were in Santorini for 3 nights and stayed at Maria's Soul Cave house. The cave house is wonderful, it had a beautiful view of the Aegean sea and right at the main Oia shopping path. The location could not have been better. There are restaurants, local stores, bars etc on the Oia path all within 2-3 mins walking. The house was small and cozy, ideal for a couple or 3 people. It was a cave house in the true sense. The cleaning person came everyday to tidy up the apartment which was great.
The only negative was the bathroom which did not have a very good water drainage system and so after shower water tends to accumulate outside the bathroom near the kitchen area. We had to keep clearing out the water which was a bit of a hassle.
Maria was a great host, she stopped by the apartment everyday to see if we needed anything. She suggested some local restaurants (skala) which I thought was great.
We would def. stay at the soul cave house again and would highly recommend it.
