Make sure to tip for room service.
Lincoln Ave has come a long way. For the most part, there used to be just motels on Lincoln Ave. They have torn down/closed up the majority. They put up a new library, police station, condos, retail, etc. As far as crime goes, check out this link:
This will give you an idea of the reported crimes in the area.
I hope this helps!
If your nervous about an area go there yourself and see if you are comfortable. We as agents cannot comment on this sort of thing. Go during the day, at night, during traffic hours, etc. See if it fits your lifestyle and needs. Also you can always check out chicago crime by block.com

As a Realtor, I can' give you my opinion on whether or not an area is safe. But there is a police station at 5400 N Lincoln where you can get some information. Also you can research the area on the internet. One of the things I recommend to my clients is to visit the area at different times of the day. Walk around the area with a friend. You will get a feel for neighborhood that way.
