Paul's place was great! It's not a Ritz Carlton, but for the money it was exactly what we needed.
Major plusses:
1) Paul and Tatiana were very quick to respond and Paul went out of his way to make sure we found his place (we didn't have cell phone service and arrived late at the designated metro station--Paul waited for about an hour to make sure we could get in).
2) It's in a fantastic location. You can walk to Attiki in 2 minutes, there's a great bakery and gyro place nearby, and it's only a few metro stops from major stations like Syntagma and Monastiraki.
Highly recommend!
