I will be travelling to Baltimore and planned to stay there for almost 2 months (will be working at hospital there).
Which areas are the safest and well connected to Johns Hopkins Hospital?
As, presumably, this can change from year to year, and also depend on the types of crime you're concerned about, it'd be useful to see maps of crime in the various suburbs and neighbourhoods of the city. Therefore:
Crime Baltimore - part of SpotCrime, shows where particular crime events and types occurred. Interesting but doesn't compare suburbs.
Neighbourhood Scout shows the various neighbourhoods, indicating crime level by colour. This is probably the easiest view of the most crime-ridden areas, although you'll need to click through to see and distinguish the types of crimes that occurred.
safe
to you?
