I Highly recommend Konstantinos.He is a great host .He would check every now and then if everything was ok with the place we’re staying .I was very happy the his place it was very convenient to all the historical places and close to Plaka .His place was about 2mins from the train station. The place was very clean and a large room .Next time I’m in Athens I for sure will try again to stay in his place.Thank you soo much Konstantinos
