I stayed at Smack Dab for a business trip that usually entails stress, nerves, and jet lag. Turns out, I had my best airbnb experience with Connie -- she is the warmest, most caring and serious host you will meet. Her house is a beautiful three-story duplex, very cozy and clean, well-kept and quiet. I could pleasantly work at the desk in my room when I needed to. Connie makes sure I feel at home -- whenever I would go downstairs (room is on third floor) to see a friendly face, she made sure I have everything I need. I would not only recommend Smack Dab and Connie to everyone else but also stay here the next time I come to Cambridge, no doubt.
