The apartment is quite small, but this is fine for keeping tidy and organised away from home. It has everything you need for a short break whether eating out or cooking for yourself. The bathroom is small with a circular curtain rail around the shower - this may be unusual for some people and a challenge for larger people. The bed is super-comfortable.
Don't be put off by the entrance in a narrow alley or the lack of outlook from the windows. This is an ancient city and the streets and apartment are part of how things were hundreds of years ago. it's part of the charm.
There is routinely noise from passers by overnight which can be annoying; not so bad on week days. However, this is a very busy city with thousands of visitors, so it's no surprise there is some noise.
The apartment is situated well for access to the Grand Canal and other sights; many places can be reached by walking (the bus station is only 20 minutes away). The surrounding area has dozens of places to eat and drink and lots of shops (as has much of Venice!). The supermarket is about 20m away.
Diana is a great host; she provided lots of information and left us to experience things on our own, but was always only a text or call away.
