Great for Families
We stayed at the Warwick with our baby. The room we stayed in was remodeled and the hotel provided a pack 'n play, a microwave and a fridge (in the form of an emptied minibar). Location was very central and we walked to Pikes Place Market, aquarium and space needle. There is a Walgreens just a few blocks away, which was great to get diapers, formula, etc. The gourmet grocery store across the street has a great wine selection.
The pool was out of service for the first day we stayed, but the hotel provided access to the Westin hotel, which was very nice. Once the Warwick pool was open, it was ok - but directly next to the inner workings of the hotel. It was also cold due to just being open. There were some partiers (loud until 3am), but they stayed a few rooms down and we didn't hear a thing unless we walked by their doors on our way to our flight. 
I was nervous to stay here based on other reviews, but think some changes have been made since they were written and would definitely stay at the Warwick again.
