Below, we have a set of hotels where we have reserved room blocks for a discounted rate during our wedding weekend. All of the room block hotels are within a ten minute walk of the Library, but as we are in the heart of the city, there are numerous other options within walking distance.
If you would like to stay elsewhere, there are plenty of options in and around the Boston area for varying price points. Hotels are likely easiest to come by, but there are also Airbnbs, VRBOs, and many other options!
There is a big conference in the city during this weekend, so the sooner you explore your options, the more likely you are to find something that suits your ideals.
