I did not get a chance to meet Dimitrios in person, but I had been communicating with him some time before the trip and I must say that I was very pleased by how responsive he was. I got to meet his brother instead, and we had plenty of great conversation about everything and anything. Both Dimitrios and his brother Yannis seem like worldly, intelligent and interesting people.
The apartment itself is amazing. Its location is phenomenal, close to everything and very central. Its got a lot of charm and many of the appliances have been in the host's family for decades.
Finally, the view from the balcony--especially at sunset, is worth every penny. I was actually planning on going out and walking around but at some point, I got captivated by the stunning view at sunset, and ended up staying on the balcony for some hours.
Everything about this place- from the hosts, to the location, to the view and everything in between-- was well worth the price. I highly recommend it to anyone visiting Athens and would gladly come back as well!
