Question Best Hotels in Trieste for a Couple's Stay

My wife and I are planning to spend a couple of days in Trieste before moving on to our next destination. We're looking for hotel recommendations that offer a romantic atmosphere, great service, and are conveniently located for exploring the city. We're open to both boutique hotels and larger establishments, as long as they provide a memorable experience. Any suggestions on where to stay in Trieste that fits this description? Also, if you've stayed somewhere you loved, what made it stand out?
