Xerxes's apartment in Beacon Hill was the perfect choice for my wife and I, for our stay during a week-long conference. We were able to escape "hotel world," yet still be only a quick Lyft to the Convention Center.
The apartment is lovely-- very clean, and private. The kitchen offers ample room and tools for preparing meals, and there is plenty of room for eating them (or working) at the Dining Room table. The bed is large and super-comfy. The Living Room is spacious and quiet, facing the courtyard of the building.
The bathroom is large, and we were provided all the amenities we needed. The little pizza shop on the corner is one of the best in Boston, and Whole Foods is only about 3 blocks away.
All in all, we loved our stay, and would stay here again on a return trip to Boston!
