We came up for a few days vacation with our kids. While a bit snug it was perfect for our group of four since two of the four were young kids.
Location was great with grocery stores, restaurants and other basics all right across the street. Location is a bit far from the usual touristy things like Smithsonian but we were fine. Several bus lines run down the street and the Metro is about a 15 minute walk away.
Host was very easy to reach. She also lives in the building. That said there was nothing to get in touch about.
The only things to note is that the bathroom frequently smelled like cigarette smoke from somewhere and there were a couple of cockroaches around we killed.
