Earlier this year I wrote a story about Joe Grunnet, a downtown broker/resident who launched an online, interactive guide to the various downtown neighborhoods.

That site debuted with a comprehensive guide to the North Loop neighborhood, including all the juicy details about various condo and apartment buildings in that neighborhood.

Of course, Grunnet, is in the business of selling real estate, so there's a handy real-time link to condos and apartments that are for sale or lease. Even for those not shopping, the site is interesting because it includes "insider secrets," price comparisons and photos of individual units and common spaces.

Grunnet said that he's added the Mill District to the guide, which will provide even more fodder for real estate voyeurs. That neighborhood, which is sandwiched between the Downtown Business District and the Mississippi River, is home to the Guthrie on the River, Mill City Museum and other attractions.

Stay tuned for more additions to the guide, including the Central Business District, which has recently become a hot-bed for luxury apartments, Loring Park and the Uptown neighborhood.
