I stayed here for a longer time, 9 days, and the view from the house is when you first step outside. I experienced a lot of beautiful dawns and sunsets. This is a quaint, small house that won't have the amenities of a five-star hotel, but will have incredible value and privacy, and was plenty of space for one person. I came in the middle of August (high season and summer), and the lack of air conditioning and wifi did take some getting used to in the hot summer weather, even with the provided fan. It cools significantly at night, though. If you get a phone and data, service may still be spotty. Santorini doesn't have any phone towers and relies entirely on satellite coverage.
I had to call Megan's friend Eri in order to get to the house; there are no addresses in the actual village, so you have to be led by someone who knows where it is. As an international traveler, there wasn't a place I could find a SIM card at the airport, so I ended up taking the bus to Oia terminal, where there is a tourist shop where I asked for the telephone. There are also some grocery stores here, and I highly recommend buying some water (legally controlled at about 0,50 euro for a giant bottle). The water on Santorini is not potable, so if you get thirsty during the night, you'll want to have something bottled in the fridge.
The steps to the house are part of the village. It looks like they're hand-cut from the rock of the cliff. Read: they're old, irregular, and do take some getting used to. I was fine with a backpack with a roller luggage and a backpack, but it's definitely about 3-4 flights of stairs, one of which are tall and steep. There are comments from other reviews that talk about mold in the bathroom. I'm allergic to mold and was very concerned about this before I got to the place. I was totally fine and didn't see any mold, so just want to lay that one to rest.
One last thing—Megan's friend Eri was incredibly friendly and checked in on me via WhatsApp all throughout my trip, once I got a phone. She offered to help me book tours and was very open to talking to me about getting around. On my first night, I had delicious fava at the restaurant she works at, where her boss was playing traditional Greek music. It was a great and magical way to start me stay.
