This apartment is spacious and comfortable, with a full kitchen and wonderful big windows that made it feel a bit like staying in a comfortable tree house. The second level (entry level is first level) has the bedroom and bath and the top level is an open kitchen and living area. We appreciated the homey feeling and the well stocked kitchen. As others have noted, it is next to the rail lines and you do hear trains going by. The bedroom is on the opposite side of the house so it really didn't bother us. This may be the most dog-welcoming Airbnb location we've stayed in. There are dog bowls set out and jars of dog treats - really nice touches. We would definitely return when visiting family in Jamaica Plain.
The only caveat is that there are two flights of stairs - if you or your pup are not comfortable with stairs, be aware that this home may be challenging for you.
