Diane's place was pretty clean when we arrived. The decor was exactly as described and she provided consumables generously. Also you're literally just blocks away from the beautiful Boston Harbor. The stairs are pretty narrow and there's no alternate option to get to her apartment - so if you're lugging heavy bags or have accessibility issues, this is probably not the place to go. Some things might not be in tiptop shape either - that wasn't a big deal to us though.
If you're in Boston for summer and for a light vacation, this is the Airbnb for you.
