We had an absolutely wonderful stay at Sue and Sarah's studio in Cambridge! First off, its location could not be more perfect: only 5 min walk from the lively Central Square is ideal for getting around town, since the T Red Line and various buses run directly from there. It's also a great hub for awesome restaurants and cafes (try Clover Food Lab and Lamplighter Brewery!) as well as a great supermarket (H-Mart) and handy places like CVS/Walgreens and Pearl Street Laundry (laundromat and wash/dry/fold service).
The studio itself was kept in great shape: a super comfortable bed and lounge chair, a really nice bathroom with a hot shower! And while it doesn't have a whole kitchen, there's enough amenities (fridge/freezer, coffee maker, microwave, glasses/plates/cutlery) to take home meals when you need a break from all the bustle. The smartlock made it very easy for us to arrive and leave at our own leisure. Last but not least, Sue was a very communicative host from start to end, making sure we were doing well and always responding very quickly to any questions we had. She made us feel absolutely welcome and comfortable.
So definitely highly recommend staying here and we'll certainly be back here next time we're coming to Boston!
