Regardless of your needs, this is a great place to stay when you're in D.C.! Three of us stayed here for three days. We didn't spend much time in the apartment but we definitely would have been comfortable. This place is in the perfect location and very walkable to everything.
It's about a 45-minute walk to the monuments and museums and I highly recommend it because then you get a feel for the city and get to check out the shops and places to eat. It's close to Dupont Circle and Logan Circle, too.
Benjamin was a great host; very responsive and gave great recommendations for places to check out. His apartment was very clean and comfortable and I will definitely book this place again when I'm in D.C.
