Overall, the Chelsea Inn is a good stay if you don't plan on spending a lot of time in the room or are only staying for a quick trip. We had a nice three nights in the hotel and even received a free upgrade to a private bathroom which was really appreciated. The hotel was easy to find, in a great location, and appeared as pictured (small, mostly just the bed, desk, and bathroom).
We did receive a message before our trip asking to cancel our Airbnb reservation and pay in cash instead for a slight discount, which we found a little concerning, but otherwise the hotel staff were easy to contact and kind. The rooms were also extremely warm and the A/C unit difficult to work, so we kept the window open at night.
Our experience was pleasant overall, but given the size of the room, the lack of an elevator (we were on the fifth floor), and no daily maid service, the price should have been at a steeper discount to a budget Hilton / Marriott hotel. This might not have been worth saving $75.
