Great location across the street from the start of the Freedom Trail. Check-in/check-out were very simple due to use of door codes for building/apartment entry. The building is on a dead-end street, so it was convenient for temporarily parking to load/unload bags.
Apartment was very clean and equipped with exactly what you'd need, although if you're accustomed to finding leftover kitchen condiments to help you get your coffee and/or breakfast going as you find in some Airbnbs, you will not find them here. There were a couple coffee filters provided!
Two caveats: 1) The apartment above us was occupied and you could hear every footstep. One member of our party didn't sleep at all one night due to the noise above. As an avid white noise/earplug user, this didn't bug me but this is a risk in this unit. 2) There is only one not particularly large sofa in the living room. For a unit that sleeps 6, the apartment could use more comfortable seating. The other options were bar/dining chairs.
I didn't really need anything from the hosts at all--their communications about check-in/check-out were clear and timely, so that was great.
