My husband and I stayed at Rhea's Inn via Airbnb for three days mid-week in early October.
The inn is located on a busy street with mixed commercial and residential development. Our windows were facing the street, but the noise wasn't an issue with the windows closed and the A/C running.
There's no attendant on site, but our coordinator, Brianna, was available via the phone and email.
The guest rooms are located on the second and third floors above the restaurant (which is not a part of the inn). We lived on the third floor. The rooms there are bigger than the second floor rooms and have a king size bed. Our room was larger than it looked in the pictures. It was light and clean and the bed was very comfortable - not too hard, not too soft.
There's a mini-fridge in the room, but no microwave or coffee maker. There's a nice place called Ma's Donuts one house down the street though.
Downtown Newport is about 5-10 minutes drive from Rhea's.
