I stayed at the Chelsea for a brief two-night stay during a work trip. It's a cool place! Definitely more of an inn/b&b feel than your standard hotel. Really neat common areas, friendly staff, and well kept. I had a smaller queen room, which was adequate for one person, maybe tight for two. Room was clean and included a tv and fridge, though not a safe. The front desk provided earplugs, but I found the room to be quiet (though it was midweek in the off season - may be a different story at other times).
Location is convenient, probably more so in season. A short walk to the boardwalk/beach,directly across from the Tropicana.
The Pub was a nice little watering hole too. Decent food, friendly staff, reasonable prices.
Overall, I'd recommend The Chelsea Inn!
