Wow! Diego's place was sparkling clean, breakfast was laid out every morning, the room had maid service... all the comforts of home, and more! I would definitely stay here again. Diego arranged a shuttle to pick me up and drop me off at the airport, too.
The only downside was that the bus could be a bit tricky at times. First, you have to physically hail the bus, or they won't stop for you. Then, you're expected to already have a bus ticket, and not all buses sell them. (Make sure to buy your bus tickets when you're in Venice.)
Diego provided maps and lots of written directions, which was great - but it's still tricky to know when to get off the bus. I ended up ringing the bell too late once and too soon another time, and having quite a hike. (Tip: enter Diego's address in your GPS, then ring the bell when you're close.)
