Walter's place is as promised--close to EVERYTHING the first timer to Florence wants to see. Fifteen minutes walk in any direction and you're there. He and his wife were prompt with communications and made check in easy. Walter also made arrangements for our o dark thirty taxi to the airport. Huge thanks for that!
Being close to everything also means city noise. Bring good earplugs; but most of the street noise died down about midnight. No need to cook; good restaurants downstairs or down the street.
This apartment is in a 300 year old building, with the combo of charm and quirk that implies. If you are out all day taking in the sites, you may not mind the presence of just one comfy chair in the sitting room; I would have preferred two. Just go prop up on the bed instead till you fall asleep from all that art.
