This place could be great for your group. It certainly seems to have been good for many people who reviewed it. The view is lovely, as pictures show, and it seems like a good space for a group to share, as long as you follow the quiet-hours rules (per signs posted in the house).
For me, quiet is very important, as I'm not a great sleeper (and earplugs make it worse). All the windows are single pane, and poorly sealed. The adjacent road is not a highway, but there were many periods when there was a surprising amount of traffic going by, and every vehicle sounded like it was right in the bedroom (and I slept in a room away from the front of the house).
In addition, there could be more little touches, like tissues, or lamps in the living room, as many AirBnB's have.
And finally, if you're heading here for the hot tub, make sure it's available before you book, as we were informed on the day of check-in that it wasn't, because they were waiting for the grass to grow before allowing access.
This may be a great place for your group. It unfortunately wasn't for mine.
