So Alex actually followed the instructions in the email from our couch surfing host (who is great!), and he actually went to the right part of town, and managed to find the place with little effort (though a bit of serendipity when he ran into the host right outside the building). So, well intentioned as my efforts to meet him at the wrong Dimitrakopoulou or between the station and there were, they were not necessary.
Today, Alex and I, and two other couch surfers Guillaume and Jane Ann went to the Acropolis and the Temple of Zeus. Then, Guillaume left to go bicycling with our host Giannis, so the three of us went to the National Archaeological Museum, wander around a park, and generally be tourists in Athens. Good times were had, along with lots of walking.
In the future, I would say to expect these posts to be shorter and less frequent. Now that Alex is here, we probably won't spend as much time in internet cafes, and also: now that I have someone to talk to regularly in english, this is not my one and only place to gush. Never fear, though, I am taking pictures! Lots and lots of 'em!
Edit: Actually, apparently Alex has a blog too. So Blogging will apparently be something we'll both be doing. I make no promises that there won't be significant overlap.
