A group of 7 stayed at Sam's place for a bachelor party, and let me tell you that we had more than enough space for everyone to sleep, sprawl out, and get ready. Also, having 3 bathrooms was super clutch.
The space is in a great location, super walkable, and is quite close to a lot of bars, clubs, and restaurants. it definitely wasn't a deal breaker for us, but it's something you should be aware of. Also, if you're looking for provisions like water, snacks, etc, you are in pretty good walking distance of quite a few bodegas/corner stores.
Overall, I'd highly recommend Sam's loft if you are looking for a space that can fit a good amount of people, are looking to be in the middle of some pretty good night life, and are looking for something walkable.
