We had a really good time in Paul & Andrea's studio. The place is just as quiet as described, easy and comfortable. Their cat and dog are super friendly and playful. You won't feel bored when you stay here for a whole day.
Although self-catering facilities are limited, you can still get the local shops and restaurant easily by just 3 mins walk. (#Fish and chips are highly recommended :P) Cheltenham station is about 13 mins walk. Perfectly located!
