4 out of 5 stay.
Meets the mark if the only time you plan to spend in the room is while sleeping and bathing. This is for a couple reasons. One, as somewhat advertised--I wouldn't consider this a "comfortable" sized room, which is the adjective used in the ad--this room is tiny. It borders claustrophobic, and I've stayed in hostels before, but with those, you know what you're getting into. Two, it's devoid of furniture apart from some night stands and the bed. A small desk with a chair so that you don't have to recline on the bed to fire off an email or do some quick work from your computer would have been helpful. Although, fitting a desk in that room would be a tight squeeze.
Overall, I am satisfied with my one-night stay and the host was good with communications and outlining the house rules. The above are not complaints, they're simply observations. Like I started with, this place meets the mark as a place to put your head down at the end of a long day checking out all that Newport has to offer : )
