3 nights in the city
We had booked in my wife and child, my parents-in-law and myself into 2 rooms. We were on the Nikko floor with a nice view of Union square and some skyscrapers.
The staff were all professional and pleasant, with door and room staff being amazing. The concierge was also very friendly and gave me some great personal recommendations for Napa wineries. I wish I could remember her name.
The room was a great size and had a large bathroom with a separate shower and bath.
I was disappointed that the in-room TV didn't have HD channels but as we were barely in the room it didn't matter too much.
The wi-fi worked well and allowed us to make good quality Skype and FaceTime calls.
We didn't eat in the hotel but the Starbucks was handy and there were good restaurant choices nearby.
If you're in town and want to shop, the Westfield Mall is a 5 minute walk away, as is Union Square.
I'd definitely stay again.
