Recommend a Hotel in Lisbon

Hi, I'm looking for a swanky, chic yet comfortable hotel for our anniversary treat.

Any recommendations. There's tons to choose from. Ideally, I'd have the budget for Três Janelas, but only have the aspiration. Not as far out as Belém, and about as far north as Marquês do Pombal. 2 nights, end of November.

Anywhere that you'd recommend?

Thanks, Emma.
