Travelocity emailed a bunch of hotel recommendations, including this one which can be booked at DO-time for $52/night + taxes:
Hotel Diethnes
52 Peoniou Str Athens, 10440 GR
Athens
It's 2-3 blocks from the Larissa Metro station. Syntagma (which will be one of our main meeting points) is 4 stops away on the Red line.
This is Travelocity's cheapest hotel offering in Athens. The next one up goes for $72+.
For those of you who remember the Levites (5:-: dwellers

) vs. the Bittites (1-2:-: dwellers

) in Ljubljana, at 2:-: this might be as close to a Bit as you can get in Athens.
