I don't know of any now but when I was a child I went to school in Cambridge Mass. and down the street from the school was a hotel, this hotel was called a residence hotel. It had quite a few older people who rented suites there, they had some nice amenities like a doorman, housekeepers, fresh linen when they wanted it, room service, someone to walk their dog when it was cold or rainy outside and the hotel dinning room if they didn't care to go out to eat, I don't know if they had kitchens in the suites then. Seemed like a ritzy staid lot to me as a child.
Now there are other types of facilities some with quite a few amenities and of course related costs. I for one am not ready for that sort of thing yet. Perhaps one day when I am writing my memoirs (as if anybody would care).
