Riccardos place is conveniently located, main tourist attractions and a vaporetto stop are nearby, but it is still very quiet. The rooms are spacious and the kitchen can really be used for cooking.
Upon arrival at the vaporetto stop you will be picked up by Arif, who is also very helpful if you encounter any problems.
Communication with Riccardo was great, he replied quickly and was very helpful.
With few simple measures the place could be even better. Most of them have been mentioned in other comments. We mostly missed working light bulbs and the Canal Grande between the mattresses was a bit annoying.
