My girlfriend and I stayed here for one evening, we've both been to Boston plenty but had never stayed in the North End. The good is that the location doesn't get much better, and the bed was one of the most comfortable we've ever slept in! The host(s) also were kind to allow me to keep my luggage in the apartment for a few hours before a flight.
The not so lovely is the transactional, cold feeling of the overall experience. Communication with Jason/Jose was prompt, I will give it that, but impersonal. After receiving what felt like a copy & paste message, and asking a follow-up question, I received the exact same copy & paste message back.
There was a gnarly dirty fork in the drawer that we accidentally began to use. The bathroom was bare with no extra amenities were we to forget anything. The fridge was empty of regular necessities for cooking were we to want to cook in the space. I recognize that sometimes hosts can counter these things by meeting guests and showing the human behind it all, but without that, it felt, again, very cold.
If all of the above doesn't bother you, and it's within your price range, it's an excellent pick. But don't expect to meet a local or feel any warmth from them.
