We stayed here over Thanksgiving and very much enjoyed our stay. There are a lot of great things about this house. The location is fabulous. We could walk to restaurants, shops, mansions, other historical areas, and the water. We rarely had to get in the car. The house is in excellent condition and feels very new and beautiful. The bedrooms were spacious for a Newport rental, and quite comfortable. The heating system worked well. We didn't use it in November, but the backyard looked like it would have been great in the winter.
There were a couple of things that kept this house from a 5 star rating - and these mostly apply more in winter than summer. First, the heat was LOUD. Every time it went on throughout the night, the pipes would bang and it woke up multiple people in the house. Second, the kitchen was not well stocked. Granted, we were there for Thanksgiving so needed more than the average guest, but at the time we stayed, there was no form of baking tray, limited bowls, no measuring cups or spoons, etc. We ended up buying a bunch at Christmas Tree Shops and leaving it there so there should be more there now.
Overall, though, we were very pleased with our stay, and think it would be particularly awesome in summer, when the yard would increase the amount of space, BBQing would be more common, and heating clanking would not be an issue.
