The much more interesting authentic Icelandic experience was, of course, our boat tour of the icebergs and the glacier lagoon. We'd arrived a few hours early before our boat tour, so while we were waiting, we walked down to the beach, and saw the glaciers were at least temporarily stranded on the beach (this happened to be during low tide). At least one was so big, Ed could stand on it.
For the week that we're staying in Reykjavik, we've rented a (very) small apartment. It's about the size of a regular hotel room, but comes with a tiny kitchen that encapsulates a two-burner stove, sink, microwave, college-sized fridge, plates and utensils, a frying pan, and the ability to make toast, coffee, and tea, all of which is quite handy; we'd been discussing just bringing in sandwich accoutrements or other food so we could eat some light meals here, and it's nice to have the ability to have a cold soda in the fridge as well.
