What we loved:
Friendly hosts
Whole floor to ourselves.
Soft bed.
Shampoo, conditioner, bodywash, lotion, powerful hairdryer!
Washer/dryer with detergent and fabric sheets.
Great heating.
Bus stop around the block near a great little coffee shop (Creative Grounds) It will take you to the Whitehouse and memorials. And when you come back on that bus, it has a stop just steps from the apartment. No need to rent a car. I do suggest using Uber if you have luggage to get you here. When you go sightsee, pay the $2 to ride the bus downtown. If you see a Metro stop (several very obvious ones by the Smithsonians) get a metro card. It cost us $30 for a three day pass and we saved so much on money. We used our Google maps bus setting and it was pretty accurate getting us around town.
There's a few restraunts by the home that are really nice. We stopped at Bacio for pizza and ice cream twice because the staff was so friendly and the food was great. it's just a 5-7 minute walk.
We felt safe walking around the area except for Rhode Island Ave. It's a busy street. Just use one of the other side streets. The houses are fun to look at on them anyways. 😉
Sorry so long but this is the things we would want to know to save some time.
