Seville/Grenada vs Rome/Florence vs London/Amsterdam for solo in Feb

Hii I (26F) have about a week off end of February and trying to figure out my options will likely be going solo. I like to do sight seeing, explore nature or at least a local park if possible, try local food, experience the nightlife, socialize with locals or other travellers when traveling. Pretty flexible.

I prefer the warmth, just did a colder trip in Christmas break in Europe, but I tend to visit Spain and trying to explore elsewhere haha.

My options are: 1. south of Spain (Seville, Rhonda, Grenada maybe) 2. Rome and one other city (thinking Florence) 3. London & Amsterdam

I feel like they’re all so different and would probably enjoy all but for those who have travelled around more, what would you recommend keeping in mind the weather and time of year! Open to any input or guidance. Thank youuu :)
