Nana is such a responsive host! We were pretty nervous upon arrival because we couldn't find the church to meet up at on Google Maps. We rented a car so we had to find the place ourselves. Therefore, Nana sent coordinates of the location instead which helped immensely.
The house has everything a hotel would normally accommodate - an iron, blow dryer, clothes hangers, q-tips, shampoo, soap, plates, cups, towels, you name it. It was very clean and exactly as pictured. We appreciated all the outlets in every corner of the house. It is also very well lit inside. There was a very nice patio area as well as a fine rooftop to get some sun and chill out at.
Finding parking initially was harder than we had anticipated. However, there was plenty of public parking spaces behind the church if you're willing to walk a few more minutes. Also, there's less car traffic there so if you're a nervous driver in Greece, we'd recommend parking there instead.
The walk from Nana's place to Thira was about 20 minutes or so. Her place was easy to find and we felt very safe at all times. The alleys are also pretty well lit so we had no trouble find our way back to Nana's place even at night.
Overall, we really enjoyed our stay at Nana's place. It was far enough from the very busy Thira but close enough to walk to it. Thank you again Nana for letting up experience a beautiful Santorini!
