Hey there, sounds rough, but have you thought about talking to the assisted living center and seeing if they will host the game? Explain to them that their client likes to play and that she can't physically make the trip anymore, so you want to bring the game to her. They should be able to provide a table and chairs.
When my grandmother was in assisted living they did something similar for her. They let her bridge group play on the premises. Of course, that was Eskaton, and they were really good as far as trying to make their clients happy, don't know who she is with or what their attitude is, but it couldn't hurt to ask. Best of luck to you,

Sounds like good advice to me.
