This apartment is beautiful, airy, and perfectly located. Annalisa and Leonardo were extremely responsive and helpful, and the apartment was full of useful info—they have created a very handy and comprehensive guide of their own to the area, and the apartment also had many local guidebooks and phrasebooks to peruse! Also: the bathroom is a dream.
Now, about that location. The apartment is right on the edge of the Mercato Centrale, which means you are right in the thick of the action, with lots of bars, restaurants, shopping, and food right at your fingertips. (For all that, the apartment is beautifully quiet.) The Duomo, the Uffizi, and all of Florence’s other cultural charms are incredibly close (10-12 minute walk through incredibly charming streets). Basically, the location is perfect.
Tl;dr: we loved this place and would stay again in a heartbeat—you should too!
