Michalis has done a great job with the house. I would call it a "Hidden Gem".
The old classic greek architecture of the house is what, on the contrary, give it it's grace. Fully equipped, extremely good location 2-3 minutes on foot to both Syggrou-Fix and Acropolis metro station, and certainly managed by a very polite, helpful and easy to communicate host. I would definitely recommend this place and will surely stay there when i visit Athens again.
Best Wishes Constantinos
