Looks nice, would stay there. I don’t know anything about the prices for your neighborhood. Make sure you’re competitive- not the cheapest, not the most expensive.
Besides that, here are some things that jumped out at me:
-The listing could use more photos. For example, more detailed shots of what’s in the kitchen in terms of equipment and dishes. Some more shots of the neighborhood, too. Maybe some streetscapes that show people and what a typical Fall afternoon looks like. Are there a washer/dryer in the unit? If so, show them. Also, a few more angles of the living room and the bedrooms wouldn’t hurt.
-You might add some colorful potted mums or whatever to the backyard.
-You mention the distance to the metro stop. From a tourist’s perspective it doesn’t give much info. How long would it take on the metro to typical touristic spots (various monuments, Georgetown, Air&Space etc etc.) Would a bus be easier, since it’s a bit of hike to the Metro stop, by some people’s standards.? Uber etc. are good but you need a smartphone. Some international tourists don’t want to pay for data. Just give a little more info about transit, so people can visualize how long it will take to some of the attractions. From what I remember about DC, your place is not that far by metro from the popular sites, but someone who has never been to DC might look at the map and think it’s further than it really is.
-Coffee. I’ve mentioned this before, but I am drawn to listings- other things being equal- where I can see a nice assortment of coffee/tea available. That way I know I don’t have to go hunting in an unfamiliar neighborhood before I’m fully awake. I know it’s silly, though apparently I’m not the only one. There was another host on here who said several guests told her they booked her place because she had a Starbucks “coffee bar.” It didn’t sound super fancy or expensive. Just some different kinds of Starbucks coffee (ground) a standard coffee pot, sugar, creamers, some syrups etc.
Doesn’t have to be Starbucks, but you get the idea. Have a nice close-up photo of the “free coffee.”
The only negative thing I saw, but this is just my personal preference, was the furry pillows. They kind of freak me out. Not sure why.
