I visited Warren for a summer weekend with a group of friends, and we couldn't have been happier with this house. It feels very much like a lived-in home; the kitchen is fully stocked with all the cookware, spices and dinnerware you might have at your own home. The back patio is right next to the river, and is a fantastic place to sit and enjoy a beer while the dog/kids/semi-inebriated adults play in the river. The wood-fired grill was a cool touch, and had wood chopped and ready to go when we arrived.
I admit I was a little put off by the high security deposit, but the owners are being cautious. It is a nice house with nice furniture and amenities - not your typical, cheap rental stuff - so they feel the need to protect themselves. Our group did not have any issues.
