Romantic things to do in Rome?

I’m planning a trip to Rome with my partner and I’m looking for some romantic ideas.

- What are the most romantic spots or activities in Rome? For example something like renting a paddle boat at Villa Borghese. I’m also looking for beautiful places to watch the sunset with a nice view over the city.

- Can anyone recommend a romantic restaurant that isn’t insanely expensive but has great food? Ideally something with a Michelin star. A nice view (rooftop, city view, Colosseum view, etc.) would be a big bonus.

Thanks in advance for any suggestions!
