The Elsyee is not bad especially in one of the superior rooms (deluxe or better) - https://www.elyseehotel.com/en/
though I've only ever stayed there when I wanted somewhere to sleep rather than on leisure.
But two words of caution - I'm not sure how it would be with a 9yo, though they are very obliging if you email queries. And there isn't a restaurant. The Monkey Bar is a good independent restaurant accessible from within the hotel, and breakfast is a real nothing to write home about buffet.
Avoid the Warwick. It represents everything terrible about US hotels.
Hope that helps.
