I would suggest "accommodations" rather than "accommodation", "receive" instead of "get", and eliminating "and/or any financial support" in favor of "or financial support".
Merriam-Webster Dictionary defines accommodation:
1 : something supplied for convenience or to satisfy a need: such as
a : lodging, food, and services or traveling space and related services —usually used in plural (emphasis supplied) tourist accommodations on the boat, overnight accommodations.
There is nothing wrong with "get"; it's a perfectly respectable word, but there are people who object to it even when the usage is unobjectionable. Many of these people are working in higher education, so to be safe you can use "receive" instead.
I think that and/or can be replaced easily by just "or" or just "and". You actually have a number of possibilities here, because there are two potential fellowships and four options with each one (neither, just housing, just a stipend, both), so there are eight possibilities. It's best to just ask if either provides accommodations and financial support, and expect that your correspondent to know to tell you which fellowship provides which benefits.
All that having been said, consider: "Will accommodations and a stipend be part of either of the two fellowships?"
