Marilena allowed us a late check-in, as she was working her friend Imisis met us at the apartment after our delayed flight. She was very helpful and gave us helpful tips about culture and the surrounding area also.
The apartment is very close (maybe 3 blocks) to Syntagma square, where you can catch the bus or train. We stopped for coffee every morning on the corner, and walked to most historical sites. Monastiraki flea market, Ancient Agora, Parliament building, National gardens. We bused to the National Archeological Museum and the Acropolis, but could easily be walked also.
The apartment was very clean and well furnished. There were grapes, bananas, biscuits, coffee and tea available too. The bed was firm and pillows were downfilled, but the shutters were awesome at blocking light. Wifi and A/C worked great!
