Not exactly true. There are wonderful neighborhoods located roughly 1/2 mile from the hospital. In addition the area near the hospital is very safe as they have guards posted at every corner. I never felt threatened in any way and I used to walk from the campus south to Fells Point. If you go in with preconceived notions of Baltimore you may very well end up hating it. If you are open minded, you may be able to find all the little gems throughout the city that make it like no other place.
While I loved working at Johns Hopkins, I have to strenously disagree. The area immediately around the hospital is quite dangerous.
Around 2 to 3 times per week, we got warnings via the hospital email about various "individuals" to be on the lookout for, or criminal activities in the area. I worked in building right at the corner of the main campus, and one of my coworkers got held up in broad daylight, across the street, getting food from a fast food outlet. I was threatened by people at another fast food outlet waiting in line at the takeout window.
While Baltimore is a nice place, and Hopkins was wonderful to work for, the City is not one of the more attractive places, and safety adjacent to Hopkins is an issue.
