We have just spent 4 nights staying in Riccardo's Theatre apartment. What an amazing place! It was so big and airy and very clean, with everything you could need supplied for you. The shower was great and the bed really comfortable. There are a lot of steps up to the apartment but it was worth it. It's in a great location, with a bus stop about 2 mins away which takes you right into Venice. There are plenty of bars and restaurants nearby including a great little cafe downstairs.
Riccardo was a good communicator and always responded quickly.
I would recommended staying here
