Sarah's house is on top of Windmill Hill so it is a walk uphill from each side. Through the park from the Temple Meads station is the nicest way. The nearest bus stop is Littleton Road on line 90 from the shopping quarter and the Centre.
The house is on three levels - from street level toilet/shower is located upstairs and kitchen down the stairs. So there'll be some more climbing when you get there.
It is totally quiet at nights so I had the best sleeps. The double bed in my big guestroom was super comfortable. Wifi worked great. The only things I was missing were a microwave oven and a proper shower to stand in - there's only a bathtub.
I would certainly choose Sarah's accommodation again when I go back to Bristol.
