This was our second time staying with Mario/Giovanna and it was as perfect as the first time.
We went in February (the coldest month of the year in Venice) but the spacious apt. was lovely and warm and welcoming.
As it is only 5 mins walk from the bus station/train we were in no danger of ever getting lost in the many 'Calles' as the 'Ferrovia' was always well sign posted throughout Venice.
We would unreservedly recommend staying at this apt.
