When an elderly person is no longer capable of or willing to live on their own, they can choose to move something I would call a "service home"1. Such institutions offer a variety of services: cleaning, food, assistance for running errands, help and supervision with medication, and other such things. These places are closer to hotels than hospitals in nature.
I would like to find a good word for such a place in Latin. I want to avoid negative connotations. Something like "service home" or "assisted living facility" (or "retirement home"?) might work, but I don't want to call it a hospital of any kind. It is a place where a person can choose to go, not a place where "old people are locked up to keep the out of the way". If possible, reference to old age should preferably be avoided, as an "old people's home" comes across (to me at least) as far more pejorative than "service home". You could say that I'm looking for an euphemism, but there is also a genuine distinction to be made — at least in Finland.
The word for an old people's home my dictionary suggests is gerontocomium. Perhaps the Greek γέρων has a more positive tone than the English "old man", but I hope there would be a more suitable word. The words for "hotel" mentioned in the dictionary (deversorium and xenodochium) refer to housing visitors and therefore look like inappropriate starting points. Another Latin word that comes to mind is asylum, but I dislike the tone. If I were to choose a word now, I might go with domus famulatoria.
Which word would you suggest and why? It doesn't have to be a single word, but I don't want anything excessively long. Maybe I have too stringent criteria there is no perfect word, but in that case I ask you to propose the best fit(s) you know. Latin of any era is welcome and attestation is not required.
1 This is a direct translation from Finnish. If a person requires more aid and cannot survive in a "service home" (palvelutalo), they can move to an "old people's home" (vanhainkoti) or "nursing home" (hoitokoti/hoivakoti), which is a big step towards a hospital-like environment. As suggested by kkm in a comment, a similar distinction is found in the US between an assisted living facility and a nursing home. I'm not aware of any similar distinction in English, but I hope I have communicated my need clearly enough.
