Karen's place is in a wonderful, quiet neighborhood that I love, and it is close to public transportation. I appreciated the comfort of the apartment, its convenience and cleanliness, and the breakfast supplies that truly allow to have a full breakfast (eggs, bread, coffee, milk). All this is outstanding.
If you are very noise sensitive, please know that Karen has three young children that you hear upstairs. It is understandable that you would hear children. However, I think it would be nice if Karen mentioned this in her profile instead of doing so only in the house manual that people get to see only after they book. Also, the house plumbing is very noisy, strangely.
At any rate, Karen's apartment worked out well for me. It was within walking distance of my son's apartment, which was great since the main purpose of my trip was to visit him.
