This is not the Ritz - but there are some really good points - it's lovely and quiet - so a good sleep was easy.
Take your own towels - ones provided were not great - I would also say take your own bedding.
One major for a couple is the double is on a mezz and the toilet is down stairs - this didn't effect me as I was on my own so slept in the single room downstairs.
Owner is lovely - and my stay in Sherborne very nice. Lovely place.
