Hill was very welcoming and helpful for my bachelor party crew. It was also good for hosting friends who happened to live nearby, since it's right off the L and there was good space to hang out. We were able to host people to watch the Super Bowl and cook up some food with the grill.
Unless you want people to be particularly cozy, the space works best for up to 10 people, based on rooms/beds and the amount of bathrooms. But for that group size or fewer, it's a great spot.
