Spent 1 night at one of George's double rooms and the next 3 nights at the one next door. The second room we stayed in upstairs was significantly nicer/newer than the one next door but both were great. The view does not get better than here.
You will see people walking near your place just to get photos because the view is so amazing. This is a VERY popular area and by no means off the beaten path. If by beaten path you mean up and down several flights of steep steps than yes. However this is right off the pedestrian walk way seconds from the stairs to amoudi bay and the famous area where people watch the sunset. If you don't like crowded then don't stay in Oia !!!
I never met George but I did message him several times and he was very responsive and extremely helpful and reliable for scheduling transfers and anything we needed.
We did have the pleasure of dealing with Lefteris (George's assistant) and he was probably my favorite person I met in my 10 days traveling Greece. Such a nice guy and a VERY hard worker. He helped us with bags to and from the location and even showed up at our door at 415AM to help us check out. He was very transparent with us about where to go and what to do unlike big hotels that are constantly trying to get you to book tours.
I highly recommend this place !!!
