I rented this unit for a relative visiting for a few nights. She really liked the unit and felt at home. I visited her there. I found the unit to be not only very clean and functional, but also warm and charming. We ended up hanging out in town quite a bit and we made some of our meals at home. I found that the kitchen was well-equipped and I found everything I needed to fix what we wanted. The building was quiet as advertised and the residents friendly. The owner was available at the times of arrival and departure, and she was friendly and helpful with any questions.
The apartment is just off Mass Ave and equally distant from Harvard and Central Squares, so everything we needed was within walking distance. A wealth of restaurants was all around, from the fancy to the diner. Small groceries stores, cafes (lots of cafes!), and bookstores, were all just steps away. Transportation was super convenient: subway stations (Harvard and Central), multiple bus lines, bikes from a city hub shared system, zipcar parking spots, and taxi parking sites were only a few minute walk away.
All in all, I would say that this is a perfect spot for a stay, whether for business or leisure. Boston/Cambridge is a great city with tons to do indoors and out. I will certainly recommend this rental again.
