July in Bristol can get hot, and with nice weather to sit outside. Liz and James' flat has a lovely apple tree to sit in the shade and read, eat out. And it is completely private from the main house. We were there to meet up with others, and had a pretty full program, so were not able to enjoy it fully, but I did spend an afternoon under the tree reading.
The flat is also a 2 minute walk from the Bedminster train station, a 5 minute walk from the bus stop (75 and 76 both stop there), and under a 10 minute walk from the Bristol Flyer airport connection. There is a great pub around the corner( The Windmill) that do good pub food with lots of veg options, and other places within a short walk across the park. There is the Windmill City Farm for kids nearby.
The only thing I wished could be better is the saniflow system that services the sewage in the flat, but there is no other way for the location, so bring earplugs if it disturbs you. We are light sleepers, but managed to sleep very well. And the bed was fantastic, with great back support. I usually dread going away because of that, but slept as well as at home. The wifi is also very good.
