Pros.
Maria's place is lovely. Pretty spacious. Central to the town. A great view of Oia and the outdoor tub is a definite plus. She also offers sweet wine from her cellar which is a neat underground, and her asst Sunil also brought white wine. Breakfast every morning was delicious! Sunil also carried our bags for us on arrival and departure. Maria was helpful in helping us book various reservations which was nice. Overall a very nice stay.
Cons
No pick up from airport as promised. She left a message by email way too late, knowing what time my flight was, saying it wouldn't work and to take a taxi and have the taxi driver call her. Taxi driver called her four times for us as he was driving. No answer, and dropped us off at the meeting point Maria had described. As Maria did not give an address to her place, only a name of meeting point, we were waiting there an hour. I had no international calling on my phone so I asked various business stores to phone her. Still no answer. At this point, a bit frantic, we were ready to try to book a hotel. Finally Maria answered a phone call and told that the asst was on his way. She later apologized and said her phone was on silent. It really was no valid excuse in my eyes.
