We stayed at Tom's place for 3 months while working in D.C., and overall the place was great but there are a few things I would consider before renting. The location is more residential than city, which suited us fine. However, the apartment is closer to a 20 minute walk to the metro, not less than 15 (at least in suits in the summer). We took the bus to the metro most mornings, which was conveniently located just minutes from the apartment and that helped shorten our commute. For a studio, the apartment is quite large and set up really well, but it didn't feel completely private. There were times when the hosts had to come in to the basement for various reasons (which was totally understandable), but there were times when there was activity in the entryway, which has windows into the apartment, that surprised us. This wasn't really an issue because we are frequent airbnb users and Tom mostly kept us up to speed on people coming and going. The bed also was not great–the memory foam should have been comfortable, but the frame it's on has these large gaps the the mattress sinks into. All of these are things I would consider if booking a long term stay, but I wouldn't hesitate to book this for a short term stay.
All in all, this apartment is a great value and the hosts were so accommodating (especially with parking–can't say enough about how helpful they were) and I would recommend it to anyone going to D.C.
