I must agree with the other reviewers here when I say I would not stay anywhere else after staying at Stratis' flat. It's right at the heart of Athens, with everything you need in walking distance. It does get a bit noisy at night, but that's to be expected if you're in a city. We had no problems sleeping. Stratis gave us some tips on where to eat and left us a bunch of stuff (bread, olive oil, coffee etc). This is a must book, so if it's free, grab it!
