Loved this loft, was perfect for 3 of us! Took us far too long to find because we didn't have good access to the internet for google maps... however once we found the place John was faultless and helpful!
If you want to stay in Oia, which 2 nights suited us perfectly (another night spent in Imerovigli) I recommend staying here, if just make sure you know the way from the buss stop to the villa before you take off.
Everything is close pharmacy, shops, restaurants and bars!
