I highly recommend Cabalto appartment within the Murano suites appartements.
The whole place was extremely clean, it had all equipment you could need and the bed was super comfy. In our suite (Cabalto) we also had a small outdoor terrace with a view across the buildings and onto the main canal. It was great for morning coffee or evening drinks.
Location wise it couldn’t be better for us - right in the middle of Murano and 2 mins from the muse boat stop where all the boats into Murano stop. It’s a quick hop to Venice main island. We chose Murano as it is a little quieter than the main centre of Venice and has a more personal feel. This does mean many places close at 5pm (including some restaurants) but there is still plenty of choice. We actually preferred this as the places that remained open after 5 felt more intimate and offered high quality food.
The appartment is run by a business who own a few apartments in the building that is situated just downstairs. They are there to answer all your questions and are very organized.
If you are looking for a Venice trip, with a base on a more relaxed island - you really should consider this place.
