We had a fantastic time in Athens at Toni's place. Check-in was very smooth and the apartment is very central to all the tourist sights and nightlife in town. Toni responded by e-mail immediately to any questions we raised. Since we had an evening flight out of Athens, Toni's staff was kind enough to hold our bags for the day after we checked out in the morning. The only possible concern is that this apartment is located in Omonoia, which the locals consider a sketchy neighborhood after dark. However, my group and I had no issues whatsoever walking around at night.
