Our small group of 6 was in Newport for a wedding.
This house is perfect for similarly sized groups - spacious queen bedrooms perfect for three couples (each with ample closet space). There is a bonus room on the second floor that would be great for an air mattress or luggage storage. The couch in the living room also converts into a bed, but it is not necessarily the most comfortable (but perfect for a night or two).
The kitchen is new, clean, and well-stocked with all the essentials. It was raining while we were here so we were unable to utilize the back deck - but it looked gorgeous and came with a large outdoor dining table with an umbrella.
Perfect location for weddings with receptions/after parties near 1st beach and a quick uber from downtown Newport. Also would be perfect for family visiting students at St. Georges (only 1/3 of a mile away). I certainly would recommend this house to other groups of similar size.
One word of advice - the house is not stocked with much in terms of toiletties. So be sure to bring your own soap, shampoo, etc. (but there are plenty of towels).
