We spent 2 nights at Jessica's.
The place is cute, cosy and clean. The kitchen is well supplied. However the bed is really soft so if you have any back pain that might by a trouble for you. The appartment is half below ground and half on the ground floor and because of this the place is very dark, we had to turn the lights on during the day to be comfortable.
Aside of this, there is a very nice deck in front of the apartment where you can sit to have a drink, enjoy the quietness of the place and even use the BBQ if you wish.
Jessica on the other hand has been an amazing host, making sure things would be as easy as possible for us, helping with luggage storage and being very easy to reach, should we have any question. She also gave us plenty of informations about the neighborhood and what to see in Boston.
The location is perfect, not too much in the center so it is a nice and quiet neighborhood, but really close to the subway, and also close to a hubway bike station if you are the sporty type.
