We stayed at Dimitris place and all I can say that he was the best host I ever had!
Communication with him was quick, he answered all questions needed.
His dad was a very nice person to show the apartment even thought his English wasn’t perfect but still he was such a warm person.
Apartment is located in a calm area surrounded mostly by locals, easy to reach everywhere on your foot or metro (if you are lazy to walk).
I would highly recommend you to try the cafe downstairs the apartment as well!
All in all, our stay in Athens was great thanks to our superb host!
