As others have said, it is an uphill climb to this church, which can be torturous in warm weather, but once at the top, the views of Florence are incredible. The church itself is beautiful. It is best to go on a sunny day - both for the city views and visiting the church - because the lighting inside the church is not very good. However, there are beautiful old mosaics that, hopefully, you will be able to see if the lighting is adequate.
