We really loved our night in Karine's house... we were flying back the next day, but we would have extend our visit if we could.
Karine was very nice, reactive, comprehensive and helpful (she is also French so it was even easier for us to communicate), among others she met us at the bus station to avoid us to walk with our luggages in the (cold) night.
The house was so pretty, we felt like in an American/Newport dream: nice street with wooden colored houses and American flags, porch with chairs you can use to comfortably drink your coffee, warm house with plants and books, comfy bed and bathroom...and the cuttest little garden to eat your breakfast in... The night was not cheap (for us), but it was absolutely not comparable with our other Airbnb reservations. It totally worth it, it's a very excellent quality/price ratio :)
Karine showed us places/streets to visit and gave us local maps: it was great because we had only one day in Newport and we were able to see the best of it. We love it, we would like to visit again, and take more time to relax and enjoy the place!
