If it helps, nowhere has (ok, had) hotels outside of Tblisi (and Batumi, but I wouldn't bother with that), everywhere has rooms/homestays. I would have thought English takeup - especially with younger people - is going to be better than when I went, when my little bit of Georgian I learned went a long way. Older people, it's Georgian and Russian. Assuming you are prepared for a less than 1st world experience, you are likely to have a wonderful time, I can't see that the astonishing hospitality I experienced will have changed.
You haven't mentioned how you are travelling, if you're cycling, good luck. There's a travel advisory against going into south Osetia which might be a route you take to upper svaneti, I would suggest heading west before north. If you have the opportunity, it is worth visiting David Garegi, and I preferred Shatili to the Svaneti. Both are glorious, but the Svaneti was being developed for tourism.
Anyhow, I would use Airbnb to get an address in a town, if they don't have a bed, they will take you to their cousin or some such.
ETA - realised you're cycling, scrap David Garegi, it's the other end of a desert with nothing much in it, beyond the hulk of a command economy village built where nobody wants to live (except for cows, they poke their heads out the ground floor windows and haven't quite worked out how to get upstairs to the hay. Shatili is also more remote and isolated than Svaneti, so probably not worth the bike detour.
