I had a great stay at Marella’s. Her place was central to my tour meet-up points, plus it was quite easy to walk to the main attractions. There was a slight hot water issue (not Marella’s fault), but she was quick to respond to my email and had someone to fix it right away. Would definitely recommend Marella’s. I will point out (as do other travelers) that it is a bit loud given how close to Santa Croce piazza it is, plus there is a restaurant right below; however a pair of earplugs fixes that issue!
