Konstantinos was great! He was very welcoming and accommodating when I arrived; waiting for me at the property, making sure I had everything I needed, giving me recommendations for good places to visit near the flat, and leaving me olive oil from his village. He was so nice :) The flat is also GREAT! It's the perfect size, very cool with a great vibe and the area is good as well. It's about a 20 minute walk to the main tourist spots but it's a very easy walk and you can take the metro to get there faster. I can't say enough great things about this place and next time I go to Athens I hope to stay there! Thanks, Konstantinos!
