Guido's place is just a minute away from the beautiful Santa Croce and about 10min from the glorious Duomo.
The apartment is near the top of a charming old building. It's wonderfully decorated, and has a selection to English books to read. Guido was very communicative and made sure everything went smoothly!
A note of caution: be sure to bring toiletries since these aren't provided. Even still, I'd heartily recommend Guido's place!
