I booked the Wave House for a group of 16 and we had a great time. The location is very accessible via public transportation (the A train), and there is ample street parking for folks who drive. It's walking distance to Beach 69th and Locals Collective, which is a great coffee shop that is also linked to a surfing school. We were able to quickly get ride-shares and/or drive to other Far Rockaway destination spots like Tacoway, the boardwalk at Beach 116th, the Rockaway Hotel, Thai Rock, and more.
There were sleeping accommodations for everyone (8 double beds, including a double bunk-bed), as well as enough towels, kitchenwares, etc. The house also had a lot of cooking necessities like pans, spices, coffee, etc. We felt very equipped for what we needed at the house.
There were also two full bathrooms in the house, as well as an outdoor shower which made our lives as a group of 16 much easier. The small pool in the back is fun for hanging out during down-time, and a few of our folks spent the mornings reading in the yard on chairs or hammocks.
