The view of the Caldera and the rest of Oia is amazing, just utterly amazing, the location is good - in a nice part of Oia, only a 10 to 15 min. walk to all of the shops/restaurants and there are a few cafes / mini-mart, and a few restaurants all within a 3 to 5 min. walk from this cave house. Fun hike down the mountainside to the small port below Oia. A good/moderate workout to walk back up to the Cave House from the port. The issues are with the Cave House itself. If you want no frills, basic, minimal, rustic, this place is for you. If you are looking for an updated or luxury unit, don't stay here. Needs major updating, everything in this place is very old, worn and very basic. It is comfortable, but just very very basic and outdated. There are other Cave Houses in the neighborhood that are newer, more updated and better equipped. This unit is a poor value for the money - extremely rustic and dingy - granted, more updated Cave House will cost you a bit more per night, but spend the money or be prepared for a very basic experience. WiFi is fairly slow, works well in most parts of the cave house, but doesn't work at all in the back bedroom. Air Conditioning also doesn't reach back bedroom very well. It is a Cave House, so expect it to be damp, musty smelling, etc. Hot water heaters only good for 1 shower, but they heat up again fairly quickly. Shower room inside of the cave house has no hook for shower wand, so be prepared to hold that wand while washing yourself, very low ceilings and a very small, very old washing machine. The outside shower room has a nice view of the caldera, but both bathrooms are VERY basic, need updating. As with most of Greece outside of the big cities, there is no putting toilet tissue in the toilet, you must place in a trash can next to toilet, daily maid service removing that trash helps with the odor a bit. Ceilings are low in bathrooms and some doorways. Anyone 6 feet tall or grater very likely to hit their head on the doorways - especially the coach lights above the main doorway - watch your head! Lastly, the distance from the taxi drop off to the Cave House is pretty far with baggage - unless you ask for multiple porters to carry your bags, be prepared to lug your stuff quite a distance, including up and down a lot of stairs and narrow walkways. Maria was quick to respond to questions and address issues, but this place needs a major renovation, we were not about to ask for that during a 3 day stay. We were pretty disappointed with most everything except the view from the deck/patio and the location in Oia.
