I like the Sonder concept, but during the pandemic it's been especially useful: minimal human contact, high standards of cleanliness (even the remote is in a bag you have to open).
There are issues with the Airbnb:Sonder dynamic, so be aware - as others have noted - who is responsible for what when you try to get things done. My check in was a bit of a wreck, seeing as there was no one on front desk and the text with my room access came via Airbnb hours later. When you call and get past the robotic/automated Sonder options to speak to someone though, they are very efficient with solving the problem.
If you are looking for cleanliness and location you might get in a hotel with little human contact, but without the price you'd pay for a hotel, this is a really good option. Things like taking your own garbage to the chute, or paying extra for having your room cleaned, or having a responsive front desk (they just chat on their phone, sleep and accept packages), are the kinds of items they've stripped to reduce cost, which if you can live with and manage makes a lot of sense. This would all fall apart if you couldn't reach someone to help when you need it, but their email responsiveness is very good. Definitely a market for this service between Airbnb and normal hotels.
Note that as of Nov 13, the construction work in the building and outside the building is still going on. An eyesore, and loud once you're in the foyer or outside, but no massive issue.
