Are mixed use buildings a problem? I thought the normal problem in America was that zoning tends to prohibit mixing uselage types.
Here [0] is a random street i picked in Paris with mixed use buildings - looks pretty nice tbh-lots of accommodation & amenities, easily walkable, some shops and restaurants.
