If you're going to Florence and you want a great place to stay, Luca's place is the one. We loved staying there. His place is a thoroughly modernized apartment that is spacious and well-equipped. The beds were very comfortable and had great sheets and pillows. The bedrooms have interior shutters that make it pitch-black if you like that for a good night's sleep. The air conditioning was excellent - an important consideration if you are there during the warm season. He was an outstanding host when we stayed there: his communications were excellent and rapid; Luca was there at exactly our agreed upon time to check us in and and gave us a thorough walk-through of the apartment and its features.
There is an elevator that stops right by the apartment entrance, so you will have no worries with luggage or the many purchases you may make, as the apartment is just steps away from Florence's famed shopping. That gets me to location: super location, it is right near many attractions yet it is on a quiet side street. Luca's place is a short cab ride from S. M. Novella train station. It is very close to fine shopping for leather and other goods and also very close to many of the sights in Florence (David, Il Duomo di Firenze, etc.). There are countless good restaurants in the area and you can easily spend your time walking and/or wandering throughout the area.
Next time we go to Florence, Luca's place is where we will go - you should go there too.
