Murano is a great base for Venice. The room is directly on the main channel on the island. Boats are every 15-20 minutes to Venice and the lido(recommended if you have time). The accommodation is fine and fit for purpose but lacking some very slight refinements (wifi, welcome pack) but has a washing machine and dishwasher. The area is serene.
The directions on Airbnb are awful. Take the 3(direct) 4.1 or 4.2 vaparetto from the railway or bus station in Venice to Murano vernier. Turn left off the boat, about 75 metres is the apartment next door to the glass blowing factory.
Finally, watch out for the bathroom sliding door-it has no handle, my wife was trapped🤭
