Eleni was wonderful and greeted us on our arrival. She was always available with a recommendation for dinner and touring, and answered all of our questions quickly. The apartment is located super convenient to a nice area to eat and shop. Walking distance to the train/bus stations and tons of the tourist spots in Athens including the Agropolis. Great apartment that I would recommend to anyone staying in Athens.
The only part I did not like about the stay was that the apartment had a bad mosquito problem. We were there for 5 nights, and I killed at least 20-30 mosquitoes each of the 1st three nights, but not until after they bit my daughters all over their face at night. Eleni was good to bring us mosquito repellants that we could plug in to the wall, but that took a while to work.
All in all a great stay, I could have just done without the mosquitoes. Otherwise - this would be 5-stars from me.
