I've stayed at plenty of Airbnbs and this is my first bad experience. I am surprised this place has such great reviews. Sure, the location is great, but the actual apartment was of very poor quality. I completely understand that the building is very old (be prepared to hear every footstep from the floor above you and for every step you take to be extremely creaky), but I just couldn't get past how bad the rest of the place is. It was as if no effort was made to maintain the apartment. Dingy, dirty shower, duct tape on tub, an extremely uncomfortable creaky bed (pairs well with the creaky floors!), no amenities. Nothing really felt "clean"...
I hate leaving a bad review but I was very upset with the quality. Just steps away is a ton of history, the desirable North End area, and tons of restaurants.... but how sad it is that such a historic and expensive building is so poorly maintained.
If I could go back and give myself a piece of advice before booking: don't do it.
