Alicia is a very friendly and welcoming host, and the whole process of booking, communicating by email and text, checking in, and checking out, was very smooth.
The apartment is on the ninth floor of a block overlooking the Hudson River. The guest room is small with a single bed raised on a bunk and you need to use a small wooden stool to climb up to it, but the mattress is very comfortable. There is a small en suite lavatory with wash basin. You take your shower in the family bathroom at the other end of the apartment. There is a small desk in the room with a view from the window towards the George Washington Bridge, but there is also a large table in the adjacent dining room at which you could do some work if you needed more space. The guest room is also next to the kitchen, should you wish to use it. Overall, this is a clean and comfortable place to stay.
The location of the accommodation is excellent. It is less than three minutes' walk to the 145th Street subway station on the 1 line. It takes 20 minutes to Columbus Circle (59th Street) and 25 minutes to Times Square.
The neighbourhood was not especially appealing, but to be fair I didn't explore it at all. There is a Rite Aid pharmacy, a McDonald's, and a couple of grocery shops near the subway.
Given the price, Alicia's guest room is tremendous value.
