Jay's Apartment was very nice for our 4 day stay in NY. It's close to several nice restaurants, at least 2 grocery stores, a nice deli, and just a few blocks from 2 different subway lines. There are nice views east and north, so lots of light. One bedroom is street-side (not avenue) so it's a little noisier but not too bad (it is NYC after all), and the other is in the back so much quieter in terms of street noise. The kitchen is adequately stocked although we only used it for breakfast and pm appetizers. The AC worked well plus both bedrooms had floor portable AC/fan units & the front bedroom has a ceiling fan.
The major dings are largely unavoidable, I think, and are likely due to this being an old building.
First, you will have to climb a couple of flights of steep, narrow stairs to get to the apartment. Keep that in mind in case anyone in your group has physical limitations.
Second, the water runs hot & then cold, literally, when showering. I assume it's when other building residents run water or flush, but be prepared to dodge the water in the shower when the temperature shifts.
Third, we decided that a troop of monkeys must live upstairs. In reality, it's a young child, but every time (s)he threw a tantrum, we heard it, including our last night at about 3am when the child decided to jump up and down & pound on the floor for about 15 minutes before an adult intervened. At least at other times we were awake or soon to be.
Finally, while mostly clean, the grout around one toilet has some mold in it and a few other bathroom areas could use a good scrubbing. The bedroom pillows are old and should be replaced. I doubled up the pillowcases as a result.
