The apartment we stayed in was easy to access and neat, clean, nicely styled and quite spacious. It was well appointed and quiet too.
The area is a 5 minute walk from 8th street/Capitol Hill, which has plenty of restaurants, cafes, bars and grocery store. You can catch two of the five DC Circular around the corner, which at $1 is a very cheap way to explore DC, although we also walked one evening from the apartment to the Capitol Building and that was only 50mins.
The apartment had a few stains.marks on carpeting, but not a major issue. The TV had no tuned channels, but it did have a chromecast, which we were able to work out to watch something one evening. The washing machine was great to have after a week of travelling. There did seem to be a rather noisy AC unit in the front cupboard, adjacent to one of the bedrooms, that ran even when the central was off - we think it may have been for the common areas? We just ended up turning the power out for this overnight so we could sleep.
The only quirk for me with this booking was that it wasn't the 'usual' Airbnb experience where you're dealing with an individual host. Sonder seems to be a large chain of what previously would probably have been serviced apartments?
It just added a bit of extra admin, in that you had to go through identity verification with them (despite being verified already on Airbnb) and download their app, etc.
Just made it a little more fiddly, but it's one of those things that once you know it, it would be fine next time (it's just not something I've experienced in Australia or Europe with Airbnbs before).
