First the good: great location, great comfortable bed, great communication from host, easy check in.
The bad: the entry and stairs are not good for those with big luggage, very tight area. The bathroom is very small and cramped, my knees touched to vanity while sitting on toilet. The shower head is very loose and is hard to get to stay in upright position.
This is just what I think you kind of get in the old neighborhoods around Boston. The place just needs some more improvements. But for basically $100/night (at least) less than hotels in the area, especially when you factor in free parking, this place gets the job done.
