I stayed at Nadina's Everland apartment with 3 friends for 3 days and it was perfect. The apartment itself is clean and comfortable with lots of style and room. It also has a very cute balcony so you can sit outside and listen to neighborhood sounds or smoke a cigarette while taking in the Athens weather. The location is also fantastic. It is right in the center of things, and it is a short (maybe 20 minute) walk to the Acropolis and other hotels, etc. where you can catch tours to places like Sounia (for the Temple of Poseidon). There are residential streets about 100 feet away that are bustling with cool cafes and bars with great food and music. Athens stays up late so it was wonderful to just grab food and beer on extremely pretty streets right next to the house. Nadina herself is terriffic and was incredibly helpful. She was available to give us information at all times during our stay, gave us great recommendations, arranged our cab back to the airport, stocked the fridge with food for us on our first day, and is generally just very warm cool. Both she and her apartment are reasons to visit Athens all by themselves (even without the gorgeous views from the Acropolis, rich history, and proximity to stunning and swimmable beaches).
