You might think a hotel without an elevator would mention that upfront. Nope! You're thinking of a better place than the Chelsea Inn. That should be the headline, but it's hidden in the POLICIES section of their listing. How is "no elevator" a POLICY? Hope you like carrying stuff up narrow staircases!
Did you want a room where you could control the temperature? Sorry, not here; they only turn on the heat at night, so if it's cold out and you sleep late, expect to freeze. Did you expect wifi because it's listed as an amenity? It exists, but when it works it's virtually unusable; it disconnects often and is unusably slow 98% of the time. Want to leave your bags at the front desk? Forget about it! Regularly scheduled room cleaning? Or a sign you hang on your door to request cleaning? Nope. Want to change rooms? You'll need that approved by someone offsite; the person at the front desk isn't empowered to help guests.
For a closet, there's an 18-inch-wide particle board cabinet from Ikea's bargain bin. There's no phone in the room, and (obviously) no room service. There is no lobby. Only registered guests are allowed in the rooms, so don't expect to have any friends or relatives stop by.
This may well be the worst hotel I've ever stayed in - and I've stayed in places that smelled of mold and had no blankets, and in places that rent rooms by the hour to guests who see that as a benefit, if you know what I mean. I would put the Chelsea Inn in the same category as those.
