Leonardo's house is a gem! A lifelong Venetian, Leonardo is friendly, communicative, and excited to talk about his City and his house. The room is the top floor of his house. Folks noted the lack of locks: this is only for the room itself. The house is well locked and your belongings will be very safe. The suite does not have a lock, but we felt secure - we've been in many airBnBs and when you stay in a room in someone's house you don't always get a lock on your room. The rocks people described were to hold the big old room doors closed.
The suite is so quiet at night and the neighborhood has a local feel. It is easy to walk to everything from here.
Do note: the bathroom has a small apartment-style bathroom/shower, so it's tight quarters and the sink area doubles as your shower. We were ok with this, but be sure you are too.
Overall, great. Thank you, Leonardo!
