A City Like No Other
DC was absolutely wonderful. Going in mid-October was the perfect time since the weather was nice and cool, so I did not get too overheated when walking everywhere. Most of the museums and attractions are free, so it is very easy to save money and still see everything. The air and city are so clean. It is also pretty easy to take the trains/buses around (instead of taking ubers).
Insider Tip:For those who love cats -- there is a cat cafe around Georgetown. I was unable to go since I did not discover it until the very end of my trip and it was closed, but if you are in the area it would be a fun story to tell how you went to a cat cafe! Also, make sure you watch the amounts on your smart fare cards for the trains, I am not sure how mine diminished so quickly after one or two rides. A bit spendy for the "per-trip" fares so you may want to look into a pass if you are staying for a few days.
