I enjoyed my stay at William's flat. The room was large and comfortable, the roommates very nice and welcoming. William was easy to communicate with and replied to questions quickly. The place is kept super clean, and access to many bus lines was right out the door, along with pubs, restaurants, groceries, even a cheese shop.
My only advice to summer travellers is that if you want to have the window open, the road below can be quite noisy. The window does a great job of shutting out the noise- and the curtains really darken the room in a good way, but if you want the air, you'll get the noise- bring earplugs :)
I highly recommend William's place!
