Travel guides
I've lived in Budapest for a year in total, first during a study abroad program, and then as a visiting researcher several years later. It's a truly lovely city, and if you're considering visiting (which you should!), you might be interested in my guide to the city. If you've never been to Europe before, you may also be interested in my primer on travel in Europe.
I'm currently working on a guide to the Boston area, and I expect I'll keep editing it as long as I'm living here :).
