My family of six had a wonderful stay. We felt so lucky to have such a spacious, clean, and modern apartment in such a great location.
Communication - Our hosts were always responsive, polity, and helpful. I couldn't ask for more.
Accommodations - The apartment is very large, modern, and clean. We used all three bedrooms, as well as the couch bed in the living room. It was also great having three (!) bathrooms. The combo washer/dryer was also great for our family of six, as we had quite a bit of laundry, and this allowed us to travel much lighter since we didn't have to carry unique clothing for each day of the trip.
Location - I loved the energy in the city around the apartment. There was so much good food, shopping, and it's just a great place to walk around while being completely safe. My son and I strolled around the neighborhood without a map, and encountered the cathedral, Hadrian's gate, the walls of the acropolis, Syntagma square, and more. We even walked from the National Archaeological Museum to the apartment one late afternoon, and it wasn't bad at all.
In summary, we highly recommend the apartment!
