Beautiful view, but unhelpful front desk, and NOT kid-friendly
We'd stayed at Kimpton hotels before and had been delighted, so we were expecting a great getaway. Like other Kimpton hotels, Ink48 was listed as "kid-friendly" and "pet-friendly." Sadly, they welcomed pets, but not my 8-year-old daughter! We arrived to find that our reservation (which we'd confirmed with head Kimpton reservation office) was not in the system, and that they knew nothing about my 8-year-old daughter's birthday. We left our bags, wandered around New York, and came back at 3:30 when they suggested, only to find that there was still no room ready for us. The concierge suggested we go to the restaurant bar while he sorted things out, but it was a 40-minute wait there. When they finally had a room ready, the concierge told us that the price was nearly $100 higher a night than we had negotiated with the head Kimpton reservation team. I was so speechless and we were so exhausted, we headed up to the room (I figured I could work it out with the very lovely Kimpton head reservation team later, that there must be some mix-up). The concierge also added that he was sending up a "birthday treat" for my daughter.
The room was lovely, no complaints. Gorgeous view, 15th floor, massive soaking tub beside the bed -- definitely a rather, um, grownup room. Everything seemed clean and was undeniably posh. We waited for the "treat" to arrive...for 40 minutes, feeling kind of silly, not sure we should go anywhere, or if they had forgotten.
The treat wound up being two warm, slightly squashed juiceboxes with a card from the concierge.
My daughter and I couldn't help but laugh. "I don't think they understand kids," she said thoughtfully, and I had to agree.
The rooftop terrace was lovely, but we were only allowed to visit it between 5 and 5:30 pm. The concierge had told us children were allowed on the rooftop terrace from 5 till 6, but the bouncer working the elevator to the Press Lounge insisted 5:30 was the latest. So we felt most unwelcome at the top, and didn't even stay for a lemonade, for fear we would be asked to leave at 5:31. 
The housekeeping and room service staff was lovely and kind and responsive. One staff gentleman, Roshan, learned it was my daughter's birthday, and of his own accord quickly brought her a beautifully wrapped box of chocolate treats for which we were very grateful and didn't expect at all.
But I agree completely with sunseeker061: the front desk staff seemed irritated as if we were inconveniencing them with any request. I continued to inquire politely about my first reservation at the lower rate, and they continued to deny any knowledge of this, despite the Kimpton head reservation team reps emailing me to say I was absolutely in the system. When I asked the front desk to call one of the head reps to confirm what I was saying, they told me to tell Kimpton to "email 'concierge@Ink48.com'"....um??? Really?
The front lobby staff (desk and doormen) were busy chatting with each other and seemed just plain annoyed by hotel guests interrupting them. One doorman was downright peeved when I smiled and politely said I could carry my own small bag to the taxi. Generally, we found that we wanted to get past the front desk and doormen as quickly as possible -- we felt oddly embarrassed and unwanted as guests -- not at ALL my experience with Kimpton hotels in the past!
As it stands now, I have an inexplicably large charge on my credit card that NO ONE at the front desk was willing to explain in full, and now I am working with the Kimpton head reservation team to remedy the situation. All the press about the Press Lounge Rooftop Terrace at Ink48 seems to have gone to the hotel's head, and they in no way reflect the easy warmth and accessibility and helpfulness of the Kimpton brand as I understand it. 
Let it go down on the record that I've NEVER written a bad hotel review in my life -- that's how uncomfortable I felt at Ink48 with my young daughter. The view was a stunner, but that's all we will want to remember of Ink48.
