Here are well-known New York City hotels that advertise personal / dedicated concierge or butler services (short note on the type of service and neighborhood). I’ve linked each item to the hotel page or an official source so you can confirm specifics and any fees or suite-only limits.

Quick practical notes

• Many hotels limit butler/personal‑concierge services to suite bookings or to specific packages; some provide dedicated concierge only to club/club‑level guests. Check the room/suite description and/or package terms before booking.
• Services, hours and any extra charges can change — it’s best to request the specific concierge/butler service at time of booking and to confirm by phone or email with the hotel (contact details are available on each hotel page above).

If you’d like, I can:

• Pull current rates/availability for any of these hotels for specific dates, or
• Narrow the list by neighborhood, budget, or the exact concierge feature you want (24/7 butler, private shopper, pre‑arrival planning, airport transfers, etc.).
