The flat was absolutely wonderful -- clean, well-appointed, comfortable, centrally located, and very charming. It was a great home base from which to explore the Cotswolds. Highly recommended!
However, we discovered on our first night that virtually the entire town of Stow-on-the-Wold would shut down each afternoon due to a semi-annual "Gypsy horse fair" occurring nearby. (This apparently is the result of theft and vandalism in years past on the part of the fair's participants.) Shops and restaurants closed throughout the village, and dinner was available only to those visitors staying at inns with restaurants. This was very inconvenient for us, having not rented a car for the trip; luckily, the local bus services enabled us to plan around the closures, and we made sure to eat dinner and visit pubs in other towns before returning to the flat for the evening (although we discovered that nearby Bourton-on-the-Water also shuts down).
Because StayCotswold did not alert us to the above before we booked the flat, I've rated Customer Service as Very Poor. Please be aware that the horse fair is held each May and October; it appeared that most businesses were closed Monday through Friday. A small Coop market with a security guard remained open until 10pm each night.
