Single apartment within the Kips Bay Court complex. Had to pay an extra $40 for gym access. Note that if you need anything, you have to end up working with the building management company and not with Zeus. Zeus did not have any pull with the building management so we had to sort it all out ourselves.
We we arrived, there was no record of our stay with the building management, even though I had emailed with Zeus 2 days prior to confirm that our arrival was expected. Building maintenance ended up having to open the apartment door for us after almost an hour of waiting. The room came with only 1 key and no laundry cards, so we ended up having to exchange emails and phone calls to finally get this all cleared up.
There is only 1 AC unit in the apartment so the bedroom can get a bit hot in the summer, but otherwise the space was clean an modern, unlike the hallways within the buildings which are dark and dingy and smell sometimes like cigarette smoke.
All and all the location is much more convenient if you are willing to use the city bikes that are very close by since the subway is an almost 10 minute walk away.
