I was talking ro the owner of the Wellow horse trekking centre the other day and found that they have a self contained cottage on the site which sleeps up to 6.
Wellow is 5 m south of Bath and is about a mile from the village of Wellow which has a great little pub; the Fox & Badger.

Telephone Frank on 01225 834376.
The area south of Bath/Bristol has 50km of BOATs. We can make 2 full days out of riding these and the standard varies from easy (exiting on road tyres) to hard.
It is within striking distance of the Fosseway roman road (again another full day) and even south Wales.
We are happy to take people round the local lanes if you want to get in touch. You can contact me (Chris) if you wish on 07738 479921 to discuss.
