The cotswolds are a range of hills in the centre of England, stretching south from Gloucester and the river Severn to the market town of Cirencester. Little villages and hamlets lie, tucked away, in its hills and valleys. Many towns have weekly markets and most have pubs and cafes.
The major towns in the cotswolds are:

Although this is central England, you may find locals speak with a heavy gloucestershire accent.
As you'll find all over Great Britain the cost of public transport is high (compared to mainland Europe, Asia, Africa, etc...).
Move this to Great Britain? Note: It is possible to buy a Young Person's Railcard if you're planning to spend much time in the UK. This gives you 1/3 off, but it costs about £15, so it might not be worth it. These can be bought from any Train station ticket office. You'll need a passport photo.
Trains do exist between some main towns, but the trainline from Cirencester was axed 30 years ago.
As Bill Bryson said, this is the only option to see the cotswolds. He was probably right.
Note: Take care on commons of the cows (they stand/lie in the roads at night time).
The bus services in the cotswolds are painfully useless. Many villages will only get one bus a day, or some only one bus a week. Even large towns, such as Cirencester and Stroud only get one bus every hour.

The area is very safe, with little crime. (The headlines of the local news paper a few months ago read "Butterfly found in carpark").
