Svartlamon is the more alternative area in Trondheim, just a little walk outside the city center. It's colorful and will make you all smiling and happy, no matter what mood you originally were in. Don't expect too big of an area or too much interesting street art, but it really is a place you can't miss out if you're interested in such and in the city!
Also - I've only been in Svartlamon in the morning, but saw some cute stores and cafés around which might be worth checking out. So i'm pretty sure it'll be more lively and nice a little later in the day or maybe even early evening.
And yes, it's a "normal neighborhood" indeed, so keep in mind that there's people living there, too. :) read more
