I can only comment about my neighborhood, and I love it! My husband and I just bought a rowhouse one block from H St, and despite any negative comments you may see on here, it really is a great neighborhood. You can walk to restaurants and nightlife, our neighbors are friendly, street parking is easy (as long as it’s not Friday or Saturday after 6pm, then it can be an issue), and the bus makes it pretty accessible to the rest of the city (as well as Bikeshare!).
When we initially started our home search, we had a boundary of Florida Ave on the north side. But honestly everything is changing so quickly, so this may no longer be the case. I can’t say enough positive things about our realtor, Jennifer Myers, and her office is now located conveniently on H St! Good luck!
