Pros:
The area is great. You can walk or take public transit for most things.
The price is good for the area. We stayed 10 days. While I would probably consider the cost of 10 days to be more appropriate for a month of rent for similar arrangements, that's just Airbnb and DC. I booked this place because it was the cheapest stay in my search bubble for 4+ stars that had the amenities we needed.
Speaking of amenities, it's got the stuff that hotels don't; washer and dryer, full kitchen with a dish washer, the privacy of a home.
Marc communicates reliably. He always made sure to get back to me quicker than expected.
Check-in and -out was super easy.
Cons:
I was unable to connect to the internet and work for the majority of the stay. Marc said this was not typical, and I see no other reviews mentioning this so I am pretty sure this is a one-off situation.
Guests have no control over the temperature. AC is on during the day but off at night, so summer stays include sweaty sleep.
It's a little dingier, in general, than the photos let on. I think they must have been taken before many stays happened. Not a huge deal, but there are noticeable differences.
Conclusion: It's better than a 2 star motel. In the end, it's worth it and I would recommend the stay to someone on a budget.
