Massimo is a great host. He is busy but makes time for his guests and is very responsive. This place has an excellent location... it is steps away from the Duomo, the Ponte Vecchio, and from the main plazas of Florence. There is NO better location to stay in Florence than this area. We enjoyed the ability to step in and step out all day long on a variable schedule. The apartment is newly renovated - maybe a year or two ago - and everything is new and functional. The sofa-bed is also fairly comfortable and our children had no issue. The appliances are new and work well. The only two minor problems we noticed were that the bathroom plumbing can sometime give a bit of a stink due to reverse flow gases in the pipes, and the other issue is with cars. You cannot bring your car all the way to the apartment due to inner city zoning issues which require a resident permit. Our host Massimo was helpful enough to advise us where to park for free and help us bring our luggage over into the old town area in his car that has a permit. The apartment is on the fifth floor and there is a nice quaint elevator to take you up there.
Overall Massimo = excellent host and one of the nicest Italians we met on our trip - he has lived in Florence since many decades; location = the BEST; apartment = clean and new; lots of restaurants and entertainment and sightseeing around. You really cannot ask for a better Florence experience than this!
