Yeah, it's moved a fraction north now into the city, but that area would be a horrible place to stay, despite the many plush hotels - there are few good restaurants, only expensive (and soulless, and dead on the weekend) bars, and it's a ways away from anything interesting either on a touristy/culture (except St. Paul's) or tech basis. Hmm. From the above it seems to be user generated though, but interesting. There's a juxtaposition here that I wonder if the OP could exploit between good reviews (hotels, restaurants) and the sort of livability/walk ability ideas that some of the other posters have mentioned.

Love the design, look and simplicity of the app though very nice.
