I had a very pleasant week-long stay in the Lincoln Room off of Dupont Circle hosted by Team. The accommodations were charming and comfortable. And the location itself could not be beat: less than a 5-minute walk from the Dupont Circle Metro Station in a neighborhood full of cafes and restaurants of all sorts, and lots of people walking back and forth at all hours of the day.
I communicated with my hosts via the Airbnb app or website. They were always very responsive to my requests and struck me as genuinely interested in making my stay in their room as nice as possible.
Although the charm of the place had to do with the period accommodations, the age of the room was responsible for a handful of problems. For example, the water pressure in the bathroom sink was very low, barely creating much more than a trickle.
The electrical wiring was, I imagine, typical of construction of that era, meaning there were a small number of outlets at floor level, and some of those obscured by furniture. Since I travel with a bunch of consumer electronics - phone, tablet, laptop, and camera - I was glad I brought along a multi-port USB charger with a long power cord so I only needed to use a single outlet to keep everything charged. I would recommend doing the same if you're bringing several electronic devices with you.
The furnishings, like the room, were charming, but a little rickety. In particular, the drawers to the dresser were hard to open and close. It seems to me like this could be easily remedied.
My biggest problem with the room had to do with the HVAC. The AC wasn't working the evening I arrived, but the hosts were quick to provide a window AC unit the very next day. Oddly enough for May, the temps dropped and I found that the heat didn't work when I went to use it a few days later. Again, the hosts were quick to respond with a space heater. That said, I don't think these HVAC problem are representative of the usual condition of the room.
All things considered, I enjoyed my stay with Team. The location can't be beat, and whatever small problems I had, the hosts were eager to help out.
