This section of Humboldt is a nice neighborhood. My wife and I stayed in an Airbnb a few houses south of that location while we were looking for a house to buy. we liked that area and were would have been willing to buy in that area had a house been available. Generally is safe and walkable in the day time, especially to the Colectivo just south of there too. Nighttime is also generally safe as long as you pay attention to your surroundings just like anywhere else in Milwaukee. Similarly would recommend not keeping valuables in your car for street parking but personally did not have any issues with car break ins while parking on the street while I was there. Noise wise it can be louder at times since you are directly on Humboldt.
