Gosia is a lovely person; her home is light and clean and filled with beautiful art and sculpture from her travels.
I felt so comfortable staying there for a month. My room had a desk to work at, which I appreciated. The location is convenient - walk to cafes and supermarket, an easy bus ride into Harvard Square, and it is near walking trails around Fresh Pond. It was really nice to discover a new neighborhood in the Cambridge-Boston area. Great stay.
