Location, location, location!
If you are visiting someone at a nearby hospital or university and you are on a budget, this is the perfect solution. If you are looking for any type of luxury or want to be near fine dining restaurants or night life you are better served staying in the Kenmore Square area. We liked the Commonwealth Hotel, but keep in mind that is a different price point and that you will be about a five to ten minute drive from the hospital. 
The staff at The Best Western was very warm and compassionate, quite adorable in our experience. The rooms are very basic but could be so much better with minor improvements. They could add a few outlets for devices ( or a lamp with the built in outlet), replace broken hangers in closets and install a safe for valuables. 
One of our meals was in the adjacent giant food court serving a wide range of food from Chinese (Bourbon Street) to Middleastern (Sepal). Both were very good, filling and under $10 with a soft drink. The hotel restaurant Longwood was good enough and reasonable. The comp guest continental breakfast was a fruit cup, bagel and coffee. An a la carte menu was available and was good and basic.
