The cottage itself is lovely and thoughtfully done, with a nice TV and plenty of space to lounge.
At this price point however (we paid $300/night all-in) there were a few issues that we would need to see remedied to consider staying again:
(1) The bathroom, in a separate building, is damp, has an exposed fiberglass ceiling, dim lighting, and a toilet that you aren't allowed to flush toilet paper in
(2) The outdoor shower is perfectly pleasant as long as it's clean, but when it rains mulch coats the shower floor and there's no way to get it out
(3) Newport is hot in the summer - would be nice to replace the window a/c with a quieter ductless a/c unit (like a mitsubishi or something)
(4) The bed was quite bouncy, would recommend getting one of the standard recommended online beds (e.g., Purple, Casper, or Tuft & Needle)
