Hi - The artists lofts at Westinghouse look great don' t they! I live in Roslindale and my kids do a lot of activities in Hyde Park. I agree with Doug that the area is fine. Of course it is always a good idea to check the crime rates with the local police.
Additionally, if you have not been there yet please know that part of Hyde Park is very much like living in the suburbs. If you are a city dweller it will take some getting used to.
