Cristiano's place is very well located near the Santa Lucia's train station. Only one big bridge to cross which was great. We had a lot of luggages so we engaged a porter to help, which was a lifesaver. Venice is all about walking and there is a lot to do but do consider the bridges you have to cross so travel lighter if possible. Stroller movement can be challenging especially when crossing the bridges but doable.
Do note that the beds are sofa beds so it will not be as comfy as a normal bed. This place was really good value for us and location unbeatable unless we wanna stay at the Cannaregio side with our luggages.
It was by the canel which gives you a view but also quite noisy in the morning.
