Danny's place is the perfect place for a large group to stay in the city.
For starters, it's absolutely massive. We travelled in a group of 8 (ages ranging from 30 to 80), and all had our own big double rooms with closet space. The main living area is huge and splits the space, with two bedrooms either side. The elevator opens into it, and two bedrooms and one bathroom (and a cupboard of spare linens) are off to the right, with the other two bedrooms and two bathrooms across the other side.
The location is great, too. You're walking distance to several subway stops for longer jouneys, otherwise almost everything else in the city can be accessed on foot.
The kitchen is well-equipped with everything you'll need and there's a laundry room (separate washer/dryer) if needed. Towels, sheets, basic-but-good-qaulity toiletries (handsoap, shampoo, conditioner) are provided too.
Prior to the trip we had great communication with Danny, with check-in and check-out handled by his brother Billy, who was always available by text.
If we travelled in a large group we'd definitely request to book this place again!
TL;DR: book this place for your large group, it's perfect.
