Short story: I would recommend this flat to anyone looking to save money on accommodations and food while in the lovely city of Bristol, and who also want to be near the main action and visit museums, pubs, and walk along the harbor. It's within easy walking distance of many attractions, and also to bus stops, the coach station and the train station for attractions that aren't so close.
Longer story: This flat was a great find, well situated and close to everything, including various forms of transportation, restaurants and pubs. The price is right and it's exactly what we needed for our 6 day stay in Bristol--a place to sleep, cook, and shower. There were a couple of minor cleaning issues, but the response of the AirBristol team was quick, and I believe they will rectify these issues in the future. We had to pay to use the washer/dryer, which was not clear in the listing, but the price was not at all exorbitant: 3 pounds 10p to wash; 2 pounds 10p to dry, which is less than you'd pay to use a New York City laundry mat. The street noise was sometimes loud, but no more so than in any other city in the world. I would recommend bringing an eye mask if you go in spring/summer, however, as it does get very bright very early in the morning. The shades don't do a great job of blocking out morning light.
A note for Americans: the amount of switches that must be flicked in order to operate appliances in England was a bit confusing at first. There are clearly labelled switches for everything (separate from the appliances themselves): the stovetop, the oven, the microwave, the dishwasher, even the shower! This is typical in the UK, but completely foreign to Americans. So, if you happen to turn on an appliance and it seems to not be working, make sure there isn't a switch on the wall for said appliance. Even the electrical sockets have switches. If the switch is off, whatever you plug in (phone, computer, etc) will not work.
Enjoy your stay in Bristol! We sure did!
