I stayed at Serena's Airbnb (2nd floor room with private bathroom) on a recent trip to Cambridge to visit friends and watch the Head of the Charles crew races. Affordable accommodations near Harvard Square aren't easy to come by the weekend of the Head of the Charles, so I was very fortunate to find Serena's place which was a 10 - 12 minute walk from Harvard Square. The house is in a private, quiet & safe setting and was very easy to find with the directions Selena provided. The room and bed were clean and comfortable, and it was nice to have a private bathroom. The Starbucks right around the corner was an added bonus. Serena was very friendly and helpful and made me feel right at home. I will definitely stay with Serena again the next time I'm in Cambridge, and I highly recommend Serena's place to anyone looking for affordable accommodations in the heart of Cambridge.
