This will be a long review but I have to describe it to show what had happened.
Diego and Alyosha are cool and lovely father and son. We have perfect communication before, during and after our stay.
It was a hard weather the day when we checked in, storm and heavy rain. I was sent the direction from the train station before we arrived. However, I ignored the message as I thought Google maps is more accurate and easier to go along with, somemore the rain started to shower when we were in the train station. We got lost by going with Google maps, even asked the local around. I tried to message them with limited credit on my phone and they came out to find us with limited information from us. They made sure that my mum and aunt were well covered by umbrellas but they were in the rain!
They gave us basic introduction of the house and brought me out to show me the location of ports (and explained how to go to Burano), how and where to buy the waterbus ticket, recommendation of local osteria and food, and supermarket (you must try this out as it is huge but hidden in a shallow alley).
For the house, my family love it so much as it is bigger than I thought, the bathroom is huge too. All the items are well equipped (even with first aids) including the cooking pots and utensils. The selection of bedding and pillows are very comfortable, especially after a long walking day. The place is quiet and near to port, also some good restaurants. It is just 20minutes walk to San Marco and Canal Grande. Most of the spots are walking distance.
For the warm and good attitude, and the house condition, it deserves more than 5 stars. Strongly recommended!
