We ended up due to some travel fiascos staying only 1 night at George and Joanna's place and didn't get the full experience of it, we basically ended up just sleeping (which we did soundly). We loved the view and the deck was outstanding...it would be amazing in the summer time!
We found it a bit difficult to locate the apartment but mainly because we aren't familiar with Athens. George was quick to help us out as well as people on the street. As, it's helpful to read the clear instructions they leave about the electricity and how it works.
Hope to visit again!
