My friend and I came to Boston only for two days. Even though it was a quick trip we really enjoyed our time. Nat's place was in a great location so we were able to walk everywhere or use the subway. His recommendations to do a duck tour and have breakfast at Trident Booksellers were wonderful! We also really enjoyed doing the Harvard tour since it was free with the duck out ticket and Parish Cafe was a delicious lunch spot. Nat's place was cozy, clean, and had a great view of the Charles River. I'd recommend staying in the Back Bay Area if visiting. It really was wonderful!
