Maria’s place is in a great location in Oia. The apartment is basic and clean, but given location and price, it’s great.
Check-in was a bit tricky, as the listing states after 1pm not at 1pm. We arrived at 1pm and the cleaners had just started so they kicked us out and we wandered around for a few hours while they cleaned. Otherwise, Maria was very responsive and helpful during stay.
Overall, Santorini is very over-touristy. We spent one day there and it was just the right amount of time. We met a couple who had booked 4 days and regretted it. Not a comment on the apartment of course, but a general comment!
