Marco's Apartment was perfect: central as described (literally 2 minutes from Piazza della Signoria), clean, comfortable, nicely furnished and fresh beside the hot temperature outside.
Marco and his daughter were welcoming, lovely and responded immediately to my msgs. They were also great help when driving in and out to drop and collect our suitcases (as the apt is central there's ZTL - zona traffico limitato - which forbidden driving through the historic centre during certain hours without residential permit.

We had a lovely time!
