Brad & Raul are fantastic hosts and I would highly recommend them to anyone looking to stay in Boston for any length of time.
Because we were out sightseeing from dawn till dusk most days, we didn't get to interact with them that much in person, but whenever we did get the chance, they were very warm and friendly. Communication online went incredibly smooth, and they checked in to make sure we were settling in okay, while at the same time totally respecting our privacy.
Our rooms and bathroom were very nice and immaculately clean, with comfortable beds , fresh linens and a great shower. We didn't have time to watch it much but the larger bedroom has a nice TV.
Location-wise, their home is in a nice suburb rather than the city center. For us, that was a plus because it was quiet and relaxing after walking around all day, and public transport into the city is cheap, frequent and convenient, but it's something to be aware of in planning your visit (again, Brad and Raul were very transparent of this in their listing, their walking time estimates were accurate and they made sure we found our way around the neighborhood).
Overall, Brad and Raul manage to combine the level of comfort of a great hotel with the joyful experience of feeling like a welcome guest in someone's home.
