Yannis's apartment is mostly as shown and described.
No microwave in kitchen. Also, don't expect to cook because kitchen lacked basics such as proper knife set (we had to use two steak knives for general cutting) and pots and pans. From memory, there were a couple scratched-up nonstick frying pans and a medium-size pot. Lots of silverware and plates/dishes though.
One of the bar chairs was broken, which we communicated to Yannis. He replied promptly but as we didn't need the extra seating, we didn't ask for it to be fixed while we were there.
Excellent location for first-timers to Athens -- Acropolis subway 5 minutes' walk, Fix tram stop 5 minutes, Acropolis site & Acropolis Museum 5 minutes, Monastiraki 15 minutes, Panathenaic stadium (1896 Olympics) 15 minutes, etc, etc. Lots of restaurants from tourist traps to local favourites. Yannis's recommendations are reliable -- Mani Mani was one of our best meals.
Yannis was easy to work with -- prompt and helpful communication. We can certainly recommend his apartment.
NOTE ABOUT CHRISTMAS: We arrived early evening Dec 25 and were worried that everything would be shut. Little did we know that Athenians like to dine out on Christmas, so many restaurants were open. Grocery stores stayed shut until Dec 27.
