Ashamed to say it but we’ve never been to Sir Benfro as we tend to lurk around the top, middle and left hand side of Cymru. Beth bynnag, mae amser 'di dod.
Has anyone got any good suggestions for villages / small town type places to stay? As always, we’re aiming to do a lot of walking, beach, pub, historical type things, taking with us dogs, grandkids, surfboards etc. We have one adult and one dog capable of some dodgy Welsh so the occasional sgwrs would be nice. Thanks v much 
Tyddewi!
And Solfach is pretty… 
Trefdraeth (Locals pronounce it Tudrath - Newport in English) is nice, and good for surfing, I believe. It’s also within spitting distance of the Preseli mountains, and in the northern (Welsh-speaking) half of the county.
There’s a Cyd group that meets there, @Deborah-SSi would be able to tell you more, and there’s still a fair bit of Welsh around, even though, as with all proper coastal locations, it’s quite heavily anglicised, especially in tourist season.
It’s worth looking on the Best of Wales / Gorau o Gymru website for accomodation anywhere in Wales. They are a Welsh company that offer the full bilingual service, and have very good properties (like the ones we use for the northern bootcamp).
Diolch, both, I’ll have a look and consult Mrs G and the dog in that order. 
We stayed in a fabulous dog-friendly B&B Llandudoch (St Dogmaels), a little village right at the northern tip of Pembrokeshire, within walking distance of Aberteifi. (The owners have three lovely whippets.) Probably not the cheapest, but a gorgeous, arty house with great breakfasts

(But this is a fair way from Sofach, Tyddewi etc., so perhaps part of a tour of the county?)
