The Sonder units at 2 Washington are spectacular if you can get the at a good price. The hard product is outstanding. I recommend it 10 out of 10.
The soft product, as in the actual hosting is abysmal, awful, semi-nonexistent. Think of your host being a call center for a bad airline, and you have an idea of the experience I had. If there were no issues or questions, the stay would be 5 stars. If you have any issues or questions, those stars are gonna go flying off elsewhere.
My first place flooded when I used the washing machine. No one responded to pleas for support for hours. Someone eventually did, but I'm not sure if the repairman was part of Sonder or not. I was forced to move the next day against my wishes so that Sonder could "assess the damage". They could not accommodate a move even on my same floor. It was not a convenient move. The next place had a noisy neighbor (walls are not great for noise), and the entire fan and light hookup above the stove didn't work. A building handyman took a look, and it turns out the unit was never wired correctly and was left not working. Great, hope they fix that for future guests.
Of course in the move they forced on me they lost my late checkout that was approved before I checked in 2 weeks before. So I reminded them about it a day ahead of time. Would they honor it? I showed them the screenshot. Sonder's response was no—the most we'll give you is half the time for a late checkout. Great, there go my plans. How about luggage storage? There's literally a large room on every floor for bike and/or storage, and their checkout email says they have you covered for storing luggage. Oh, and I had asked about this before check-in and they never provided a response. 12 hours before checkout they say no, no storage is available in this building. But they'll give me a coupon for some public storage place?!! No shot Sonder. Not even close.
I think if they get their support act together the location could be a knockout. As it is you are going to get great light, a great bed, a new nice apartment. Just hope nothing goes wrong, that neighbors aren't loud, and that you don't need any info or support from the host
