Maria's place is extremely quaint, with fantastic views, and located in a perfect spot within Oia. My husband and I spent two nights here while on our honeymoon and while I enjoyed the uniqueness, my husband is a bit claustrophobic so it was a little tougher for him to enjoy the stay. If you don't like spaces with little natural light, it might not be best for you. It is very much a cave! However, if you want a unique experience of staying in a home very similar to the locals, absolutely do it! It was clean, easy to get to, and the people Maria has to help with your luggage, show you the house, and give helpful tips are fantastic. A few things to note: definitely, use the dehumidifier! It helps with the musty feel/smell of being in a cave (which is inevitable!). The bathroom is detached, so you have to go outside and into the bathroom but we actually thought this fun! Be prepared for some stairs! Maria's place is located below the main street so be ready to descend and climb stairs on your way to and from her place. We didn't think this was bad at all, but for those that struggle with stairs, it could be tough. Maria is fantastic, quick to respond and very helpful with any questions you may have. If you're ready for a unique Greek experience, absolutely stay here!
