We loved our stay at the Loews Regency. It's a classic, luxury New York hotel -- and all the while it doesn't feel dated (especially compared to other NYC hotels).
Rooms are large for New York City and well appointed -- bathrooms are very nice.
Staff -- from the doorman, to housekeeping, the the front desk (shout out to Vincent) are top notch.
Location in Upper East Side -- two blocks from Central Park and MTA subway. Great shopping and restaurants everywhere.
We certainly put this hotel towards the top of our list to consider when visiting New York City.
