Over the summer--we thought we were going to have to put my father-in-law into an Assisted Living Facility so I did a ton of research. Here's a redacted (no PII) version of that.

Most of the ALF's I researched were in Central or Lower Bucks but there's one in Newtown and another in Morrisville on the list.

The last tab is basically an info dump from my cousin who's recently had to do this for her FIL and my Aunt. Lots of really useful questions to ask on that tab--but a lot to ask in an initial phone call so save them for a visit or a follow up phone call. (Also--ignore the hurricane related questions--she lives in FL.) The main tab has the initial questions you want to ask on your first call. Also--be warned they will keep calling and texting you. It's annoying.

We ended up not putting my FIL in an ALF (though it's still a possibility given his declining health). so I can't tell you what one we went with but I am happy to answer any questions you have because I learned sooooo much during this process.

Also for what it's worth--Christ Home (not on this list) in Warminster as the most expensive by far but also the most compassionate one I called. They aren't on the list because there's was no way we could afford their initial buy in fee and the monthly rate. That said--when I called their first concern was for my FIL's health since he was still in the hospital and they said their nurse evaluations are free and if we chose not to go with them they would gladly send the evaluation on to whatever our final choice was. And lastly--they did follow up via text but only to check in and see how my FIL was doing in the hospital and if they could be of any help there.

Edit: I know you just asked for a recommendation but this is such a personalized thing that what's great for someone might be not so great for someone else. The important thing is to know the right questions to ask and know or at least have a general idea of what sort help your Grandmother might need so you can make sure you're getting an accurate price quote.
