We absolutely loved this cave house! Since it's in a little village a little out of the way from the major things to do in Santorini, a car is almost a must for this house, but it's well worth it since it gives you flexibility on the island and wasn't too expensive. After a little driving around trying to initially find the house (if you have google maps, search for "Guest House Kalitsi", but beware some of the "roads" on the map are more like walking paths) we found the church that Ekaterini told us to park next to. She welcomed us with giant hugs and smiles and showed us the house. The house is huge for an airbnb and we loved the decorations and art on the walls. She had some grapes and other snacks for us when we arrived. The bed was comfortable and we really appreciated the washer and drying rack since we were in the middle of a long trip. We didn't use the second bedroom, but this house could easily sleep four people. One thing to be careful of is shutting the door so mosquitoes don't get in at night. We had to go on a mosquito killing spree since we must have had it open too long. There is a mosquito net over the bed if you need it. Ekaterini was also kind enough to let us store our luggage in her house the day we checked out since we had a late flight and the luggage didn't fit very well in our tiny Smart Car. Overall, we absolutely loved this place!
