Nena's apartment is a fantastic place to stay in Florence! It's very conveniently located (the Duomo is just a short distance away), and the location feels safe. The apartment itself is beautifully furnished and SUPER clean- and Nena even provided us with slippers, which was very nice. The one thing to note is that there is no elevator going up to the apartment. Nena herself is wonderful- she is super quick to respond, and very kindly helped us with any issues (regarding both traveling in Florence and the apartment) throughout our stay. Highly recommend!
