There are beds enough for a large group. 1 King. 1 Full. 4 Twins (including the trundle). The beds weren't the best sleeping experience, but for what we got, it was sufficient. You can tell you aren't sleeping on your $5,000 mattress.
As far as the house stock, they provided enough paper products to get us going and the kitchen was complete enough to make our stay comfortable. We ended up making a nearby Target run for Keurig pods and extra toilet paper.
The two street facing windows in the front bedrooms let in a lot of light in the morning. They have blinds, but that didn't make a dent in the amount of light that streamed in. Bring a sleep mask so that isn't an issue.
The closets are locked (most likely for personal storage), but if you are planning on hanging up your clothes, there is one pop up closet in one room and some hangers above the washer/dryer on a rod in the hall, with the master having a combo rod/storage area. Not every room has a designated clothes storage solution as only the master room has drawers or a place to lay clothes.
However, we only used this home as our getting ready and sleeping area. We did not lounge around, we were out and about the whole time. If that is what you are planning as well, then this house is probably for you and your people.
Check In and Out was a breeze. The owners were very specific on their instructions and house rules list that made the experience easy and enjoyable.
Don't let these issues I mentioned prevent you from staying here. They were only mild inconveniences, not deal breakers for us. We had a great visit and would visit again.
