A perfect Cambridge nest -- exactly as lovely as in the photos; maximally convenient for our Red Line transit needs; clean, comfortable and cozy. We don't think we've ever stayed in a place with such clear and detailed check-in/check-out instructions! Carolyn was wonderfully communicative and helpful; when our schedule constraints made our original check-in time complicated, she was more than willing to accommodate our later arrival and take the time to show us everything we needed. Our stay was so short that we didn't make much use of the well-equipped kitchen, laundry facilities or garden, but we are looking forward to future visits!
As a side note, on three separate occasions, local friends suggested meeting at restaurants that all turned out to be literally within 2 blocks of where we were staying. That's what we call a truly central location!
