We had a wonderful time at Liliane's place. We came down for the holiday with our small dog and spent our time wandering around Newport and taking luxurious baths in the incredible jacuzzi (it takes a while to fill such a large tub so turn it on at least 30 minutes before you want to get in). Having the small kitchen was also really helpful; overall, we'd recommend it for any single person or couple who likes to be self-sufficient during their vacation.
One note: if you think you might want to do any baking, make sure to check with Liliane about having any baking pans - we managed to make brownies but it was tricky without a proper pan.
