This was my first trip to Boston. Chose Charlestown because my friend lives in this neighborhood. LOVED visiting Charlestown and this apartment was perfect for our stay. The place is adorable and roomy. Both the bed and hide-a-bed were comfortable. Also, has a cute patio out back with flowers. Owners live above so that was comforting if we had any issues (but we didn't).
*** The public ferry is a short walk (by the Navy Shipyard) and is only $3.50. We took it into the city and it was a lovely way to experience the harbor.
