Giannis' place is close to Oia, about a 10 minutes walk. This has pros and cons: the place was also very private. I thought it was much nicer to hang by the pool when nobody was watching from the street, which would have been the case in central Oia. Also parking was easy.
Giannis was a super host and such a warm person. He was quick to reply to any inquiry and had very good recommendations for restaurants and activities. Just do what he says, you'll have a wonderful time!
The suite was cleaned every day (it was spotless) and a little breakfast was included. Recommendation!
