Amazing apartment. The rooftop terrace is absolutely incredible and has a 360 view of all of Athens. The apartment has everything you possibly could need and is very spacious and comfortable. There is a grocery store right on the corner, and cafes, bakery, post office, etc all within walking distance. Haris was extremely accommodating and easy to communicate with. He was a great host.
Small drawbacks: As another reviewer said, there is a good deal of noise at night, but, hey, you're in the middle of a big city! And it's a bit of a walk to public transport, but the taxis are so cheap and accessible in Athens that if you have more than 2 or 3 people it's not even worth taking the metro.
