My wife and I stayed at Fabio's place for the start of our honeymoon and enjoyed every single day there. Even though my wife got a little sick at the beginning of our trip (absolutely nothing to do with Fabio haha) him and his collaborator were very helpful arranging a visit to the doctor and taking us there. She got better after that and I really appreciated the extra effort. He was very attentive at anything we needed but also not overly attentive that we felt overwhelmed. Every time we texted him he'd reply within minutes. Everything in the flat is well explained (from the amenities to the nearby places of interest). The flat is also one bus ride away (which comes every 20 minutes) from Piazzale Roma (which is the main port of entrance to Venice). All in all we highly recommend staying at Fabio's :)
