We had a wonderful stay at Rich's large, clean and comfortable appartement with a very nice terrace in a quiet neighborhood.
The centre is only a 15-20 minutes walk away. Rich gave us suggestions for the best route and it was much better than Google maps.
We received a lot of tips from Rich and they were all very worthy. The best way to get from the airport to his appartement for example. But certainly the restaurants were very good recommendations because you eat where the Greek eat and avoid 'tourist traps'. Rich is an extraordinary guide at distance.
If we visit Athens again, we would surely book his appartement again.
