We loved our two nights in Florence at Marco's place. The location was perfect with a dream view of the Duomo. There are cafes and gelato right outside the door, and everything we wanted to see was within a few minutes walk. Marco answered every message we sent him within a few seconds and was very helpful. Sparkling clean and modern, and if you are a design lover (I'm an architectural historian) you will enjoy the extra touches such as vintage design magazines and even an Erte poster in the bedroom. There are stairs, so that is the only consideration to take into account if those would be difficult for you. Otherwise, do not hesitate to stay at Marco's place!
