I think the room service was by far the best ive ever had. The bedding was incredible as well. There was a 25$ service charge for amenities which were ok but the breakfast wasn't worth 25$ in my mind. I would think that if i do pay 25$ i would recieve a better breakfast and a smart tv with just netflix or some other streaming service. Other than that, the shower was nice, and room was clean. Do keep in mind the walls are thin so people can hear most conversations if outside in the hall, unless you speak in whispers

This little inn surprised me with a darling superior king with a nicely appointed front sitting room in addition to a hallway and a king bedroom on the back. Sitting room overlooks Post St with a functional window wall over the fire escape. Very welcoming and bright. TVs in each room. Bed is very comfortable. Lots of fluffy clean towels. No air-conditioning might be a problem August-October but otherwise not an issue. Ceiling fans in both rooms. Big plus is the unlimited filtered water available no cost. Wish they had coffee service in the lobby before 8 am. Rooms have little coffee makers but only powdered creamer. Shelf stable half and half pods would be a nice upgrade. Tiny complaint. This is a well-priced, perfectly located snuggly spot in the city. I’ll definitely return.
