This place is in a great location. I can't say enough about that. We felt safe in the neighborhood. It's really close to The Pub and People which is a cool little pub and is a 20ish minute walk from near the White House area. The check in and check out were very easy. Additionally, the place was very clean. The hosts are very communicative and ensure that your stay is great. They have a great manual with suggestions for things to do in the area.
The reason I only give this place 3 stars is because it just is. There's nothing terribly great about it. To me, 3 stars means it meets expectations and does not go above and beyond.
The mattress on the bed and pull out couch were not comfortable, there were only four pillows in the entire apartment and they were flimsy, the knives couldn't cut a loaf of sourdough bread, and dishes are so cheap you can't put them in the microwave.
If you're looking for a safe place to stay that is clean in a great location in DC then this is your place. If you're looking for more comfortable accommodations and utensils that work then keep looking.
