The townhouse itself is very clean, and Irik has it outfitted with what you need for your stay. There is a power strip and lamp next to the nightstand, very convenient for all your electronic devices. There is also ample desk and closet space at your disposal.
The bathroom and common areas are very clean. While there is no ice machine, there are trays and a dispenser for filtered water. Just refill what you take.
While there is not a convenience store on the block, there is a Super Wal-Mart about two blocks away. You can stock up on what you need there, if you are trying to save money by not dining out.
I landed at DCA late after some delays, so took an Uber over and arrived around midnight. The fare was about $15, and Irik's check-in instructions are very clear. One of the best check-in processes I've had in my years using Airbnb, which is nice when you are arriving very late.
While his spot isn't terribly close to the Metro, there are a couple bus stations within a block that will get you to the Chinatown station in only a couple minutes. From there, everything is accessible to you. I found their frequency serviceable enough, even on a holiday. Not too crowded, as well.
This is a good place to stay, and a great value. I'd stay again on my next trip to DC.
