Drop him a visit? Protest outside his doorstep? Easy:

Where:

  Pagrati / Kaisariani. Thironos is crossing Formionos Str, just two
  blocks before Imitou Str. 11 is exactly at the corner of Thironos
  and Formionos. This map may help.

By bus, from the center:

  - Bus 214, stop "Ag. Nikolaos" (the next after Caravel Hotel)
  - Bus 224, stop "Poseidon" (on Formionos Str, just before Imitou
    Str.)

By metro (may not be very convenient):

  Stop "Euangelismos". From there take "Basileos Alexandrou" Ave, and
  when it branches, just after Caravel Hotel, take the right branch
  which is "Grigoriou Theologou" Str. About 200m on "G. Theologou" you
  will see some steps at your right; climb them up and you get to
  Thironos Str.

By car, or bike, from Syntagma Square:
 
  - Take "Bas. Sophias" Ave.
  - After the National Gargen, turn right to "Irodou Attikou" Str.
  - Just before the presidential mansion, turn left to 
    "Bas. Georgiou B" Str.
  - Keep going straight; after about 1000m the road you're on 
    will become Formionos Str, and cross Thironos.
