Great location. I was working in Midtown and it took about 20 mins in the morning from the apartment to Grand Central station, with just one change on the subway.
Yeah, the entrance hall is a little uncared for (but you spent 5 seconds there) and the carpets could be newer. But everything is clean and the space is brilliant for the price and location. The beds are super comfy and I found the apartment to be well equipped (though it was just me staying there).
I would stay here again.
