Summit was perfect for our purpose. After a year delay due to COVID (thank you Brenda for being so understanding and easy to work with!), our group of ~20 was down to 9 but we loved every minute of it.
The front porch and backyard are better than they look in the pictures. The kitchen is easy to navigate and has every pot, pan and gadget you could need. Spices, oil, etc. make cooking enjoyable. We spent almost no time in the house but the bedrooms were roomy and the beds were comfortable. Summit is an excellent location for biking, playing tennis, shopping, and going out for ice cream!
We tried to imagine how we would have managed with 20 and we could have done it but it would have been difficult to all gather together. Lots of space for smaller groups to gather and talk. It was the perfect house for our needs!
