Second time in Florence

Have you been to the Pitti Palace and the gardens? Hiked (or bussed) to Piazzale Michelangelo?

My friend and I needed to kill about 2 hours before a train and stumbled into Santa Croce and an American art student's last day giving tours in English.....was great!

I always use half of my time in Florence to do daytrips, Lucca, Siena, other tours outside.....

Have you seen the Michelangelo drawings at Medici Chapel? Limited access and well worth the visit plus access to the Chapel.

Palazzo Davanzati is an interesting historical house with a lace collection.

Hard to know what to recommend without a full list of what (for you) were top sites but leaving off the Bargello, Uffizi, Accademia, Duomo complex (cathedral/museum/bell tower/baptistry) and Medici Chapels (which wasn't a favorite for me):

Museo San Marco: we loved this one!
Basilica di San Miniato & cemetery (Porte Sante). Old, important and great view from up there.
Basilica Santissima Annunziata and piazza of the same name
Basilica di Santa Croce: say hi to Mike of the "David" across town. Great windows,
Santa Maria Novella; a very old and important lady
Santa Trinita: read up on Ghirlandaio's frescoes in this one.

Museo San Marco for sure
Science museum
food tour
day trip by bus to Siena

Find the flood markers from the 1966 and previous floods high on the walls --- some on streets, some in the courtyard of Santa Croce, one inside a shop

See the Pontormo in the Capponi chapel in Santa Felicita

Eat in the Sant'Ambrogio market

Bardini museum --- collection of art & artifacts in a 13th century building made into the collector's home. The last time I was there, only a couple other people were there. At the top of the gardens behind the museum there's a great view of Florence.

Santa Maria Novella --- full of art in situ

Duomo museum --- a world class museum

archeology museum (Museo Archeologico Nazionale)

Baptistery (do the expensive scaffolding tour of the mosaics restoration if that is still going on)

Brancacci chapel

La Specola --- I expected to dislike this natural history museum but loved it

Benozzo Gozzoli chapel in the Palazzo Medici Riccardi --- a tiny room where you could easily spend an hour (but you don’t have to, unlike most of the other churches, museums, & art galleries) looking at all the details of clothing, portraits of the Medici family, animals, horses, flowers, etc. I always skip the rest of the palace. The paintings covering all the walls seem to be saying “We Medici are like the three wise men bringing gifts, so it’s OK that we are filthy rich.”

Ospedale degli Innocenti

Look for Clet Abraham’s clever altered street signs

Take a class at the British Institute

The Bardini Gardens are lovely.
Take the local bus up to Fiesole, it only takes about 20 minutes.
There’s a great Roman site with an amphitheatre and ruins.
Also if you walk up a steepish hill there you have a great view over the whole city of Florence.
Go on a sunny clear day.
I went last September and there was hardly a soul there.
Take a short train trip to Prato or Pistoia…go on market days.
Or the other way to Arezzo.

Take a wine or food tour or a pasta making class. Visit the Oltrano neighborhood and see what’s going on in Piazza Santo Spirito while you’re there.

We took a 3 hour guided tour by Airbnb experiences, specifically geared towards the Medici family. It was fascinating. We went into some buildings off the beaten track I had never seen before.
