Pros: Spacious place though expect to travel back in time. It is a Grandma's house after all. You will need to figure out how to start the stove from the breaker box.
Close to the crazy main street.
Owner lives in Athens but was responsive by phone.
Cons:
This is not for the house but for that location in Oia. , The place is overloaded with tourists. they are pouring by the thousands from other quieter places in Oia just for the sunset which is not even the best in Santorini. Go to Pyrgos or the Akrotiri Lighthouse for the best sunsets.
Hard to find parking between 7 PM and 9 PM due to tourists coming for the sunset.
No AC means open windows, slammed doors and lots of noises at night. If you are not skilled in securing the windows with the rocks provided they will rattle all night. Our kids (8, 10 and 13) thought it was haunted and they all crammed in one bed during the night. Being three, we found one sleeping in the same bed with the other two with her back to the wall like a drunken sailor. This is not a hotel experience, as long as you realize that before booking , I think you will be fine.
Wifi is seriously underpowered and works only in the room where the router is (the room in the back with the bunk bed). So get yourself a GSM card with plenty of data and do a hotspot. We travelled 7 (two families) and one had to go to the hotel to get wifi for work purposes (rare case but many do need to work even in vacation).
We were told that a previous guest moved the wifi router from its central location but when we tried to move it in that place it did not connect to the ISP so we had to move it back.
The back of the house leads to some unsightly dirt land but that is I guess expected in Santorini.
I would not go back here, not because of the wifi (as all I need is to get my own wifi router with me) but because the location and lack of AC
