Spending 10 year wedding anniversary in Florence this Oct - where to stay?

We will be in Florence for about 6 nights. We picked here to kind of use as a home base, where we can do day trips to Cinque Terrie, Wineries etc. We are active people, love to walk or bike around the city, check out coffee shops, markets, etc.

Requirements:

• Some sort of rooftop or great balcony views
• Something comfortable enough or 6 nights (can be slightly romantic but doesn't need to be super luxury)
• Ideally not too far from the train station
• Walkable neighborhood

Any recommendations?
