We stayed over the 4th of July weekend and the three of us loved this quaint little apt., it was very private and quiet (if you don't count the fireworks that were going off until all hours throughout the city!)
As described the apt. was about a 12 minute walk for us to the nearest T (subway) station which allowed us to leave our car behind and use public transportation to get around Boston rather than paying for parking everywhere.
The apt. was a comfortable size for three of us, and her newer deck overlooking her garden was a great place to start each day with a cup of coffee and watch the birds and squirrels while we ate breakfast in the morning, or enjoyed some wine and cheese in the evening.
