"Not very safe"
I have been through E Tremont Ave a few times. It is pretty much made up of a lot of low income families, rundown buildings, and shady looking buildings. The streets are pretty much filled with people looking for a quick buck, be it through theft or selling drugs. I know this because my brother is a police officer in the area and there is a lot of crime activity in this area. I know from personal experience that you should watch your wallet or purse on this street, as there are pick pocketers who are very skilled at this. One evening around 7:00pm a friend and I were walking down Tremont (going to pick up something I found for sale on Craigslist, which was actually a big mistake and shouldnt have even made the trip there), and a guy approached me asking if I had a couple dollars to spare so he could get a cup of coffee. I told him no and kept walking. The next thing I knew he bumped into me from behind, said sorry, and just ran off past the front of me. A few minutes later I checked my backpack and the front was open, my day planner was hanging out. He had gotten away with a small coin purse I had had, which had about $40 in cash folded up inside. After that we didnt even make the attempt at finding the residence we were looking for. I just called my brother who was on patrol that night and alerted him to the theft. Of course the guy and my $40 was never found.
