Apartment is rather plain and minimal, but it's fine if all you need is a place to crash. Directions make it easy to get to, and host's sister who lives in the building was quite friendly greeting me. I would note that it's a 10 minute walk to the metro at a /brisk/ pace, closer to 15 if leisurely or carrying luggage. Also, took me closer to 80 minutes door-to-terminal to get to airport by metro (although that was with an admittedly long wait for the train... your mileage may vary). Don't take the bus connection at rush hour, it will be much longer than 45min. You can get to most tourist destination in athens by metro, and it was nice to be close to a station.

The apartment itself is bare minimal, but comfortable unless you're extra picky. Some people might get weirded out that there's no showerhead or shower curtain, and bring your own shampoo. Like others mentioned, place gets a good amount of street noise at night (it's easy to find because its on a main street)... I'd be more cranky about it had I not gotten ear plugs on my overnight flight. Nevertheless, place is fine if all you need to a quick no-nonsense place to crash. Host's sister watching over the place in the building is friendly and checks up on you to answer any questions you might have. Overall, thanks for giving me a good home base on my trip! : )
