300 year old homes have their quirks, it is part of their charm. We very much enjoyed our time at The Knoll but noticed several quirks you might want to consider. We have stayed at many rentals (our primary vacation method), we've also stayed in the Cotswolds many times and have owned our own rental in the US.
Overall the owners have done a terrific job pulling in modern conveniences while keeping the original beauty of the home intact. The garden is absolutely lovely! The wood burner in the fireplace lends romantic charm. However, the placement of the stove-top (in the gorgeous kitchen) is less than ideal. If you are over 1.7m you will find cooking on it a challenge as large beam (with an adorable "Duck or Grouse" sign hanging on it) is directly above it. But many people never cook at all on vacation and otherwise the kitchen and the appliances are first rate. The washer/dryer is by European standards what most folks are used to, but if you are from the US and thinking you'll do your wash mid-point in your trip, you'll need to plan carefully (it is less than half the capacity and 2-4 times the cycle time compared to what you're used to).
Speaking of tight places, while the ground and first floors are charming and easy for 2m tall people. The top floor bedroom/ensuite would be difficult for 2 people over 1.5m to share. A single or 2 children might do well there. My wife and I chose to stay in the smaller bed and less convenient bath on the 1st floor rather than take our chances upstairs. Note that children under 5 years aren't recommended due to the nature of the stairs, and full grown children would suffer the same height restrictions, so this bed/bath is limited in function.
There are many scenic and picturesque walks to be had about the town. The cafe had perhaps the best Full English Breakfast I've ever had and excellent coffee. The store had a good selection of items. These are next door to each other and a short walk away. The pub/hotel across the street I cannot recommend. Limited choices and the bar smelled of cigarettes and the food was so-so. The people were friendly, though. The Great Western Arms not far away was not friendly at all, but was very cozy looking inside. Despite the sign, dinner really is only served from about 6:30-8pm, so we never actually ate there.
The street is narrow/full, but we could usually get parking within 150m. It's a quiet town but lock boxes are poor security: you know that code never changes.
