Dirty, Smelly, Unsafe, etc.
I've tried to be as specific as possible for other travelers. I also hope that when Best Western management see this review, it will help to identify areas in which they can improve.
Poorly maintained historic 'round' (hence the name Roundhouse) hotel located in a high traffic and industrial area in Roxbury. Very loud and noisy and currently, the trash dumpster get emptied around 2:30am. At least that was the schedule for the days/nights I was there. Large trucks with their back-up beepers blaring 24/7. Close to hospital, so blaring sirens 24/7 also. 
Very limited parking. Area is prone to lots of foot traffic...park at your own risk! Did NOT feel safe walking from my car to the entrance at night.
Busy gas station next door with bright lights. Curtains did not block out the light during the night. 
Drafty, ill-fit windows allowed cold wind to blow directly in as well as all traffic noise. I used the couch cushions to try and stop the cold air, but it did not work.
Unclean and stale smoke smell through out the entire hotel. When you first walk in (manual doors with NO handicap opener) you can smell freshly baked cookies...I thought UMMMM, UMMMM! But as you ride up in the elevator and step onto the floors...your greeted with dim lighting, dark decor, and smoke. The smell in the rooms only gets worse...
Internet is slow and I was unable to sustain connectivity for work purposes and I ended up using my personal air card.
Stained and peeling wallpaper throughout the hotel, broken tiles in the bathrooms, towel bar falling off the wall, broken lid on back of commode, broken curtain rods, torn curtains, rust stains in the tubs, broken toilet, and I had a leaning toilet! 
Carpet is filthy. I kicked my shoes off when I came in....ended up throwing my socks away because they were black!
Sheets are well worn, but at that comfy stage instead of stiff and starchy. Toiletries not restocked. Had to go to front desk to get shampoo!
The little two-room suite are large enough. Has a nice size desk, newer desk chair, small microwave and fridge. Older model TV's and even a small safe in the armoire.
