Luca's place was nice, conveniently located, and Luca was an excellent host. Very responsive and kind. One thing I would caution is that the apartment is very noisy. You can easily hear neighbors talking above you as well as everyone walking outside.
If you don't mind a little noise, this place is a great value, and Luca is a great host! It's in a great location, close to all the great restaurants in Trastevere, and feels very safe.
