To begin with, this apartment is located quite close to Piazza Roma station. If you are arriving by train, you don't need to cross any bridges to get here. However, if you are arriving by bus, you will need to carry your luggage over 1 big bridge.
The apartment is very close to water taxi station. It has 2 bedrooms, 2 separate bathrooms (not attached), 1 kitchen & a living room. There is air conditioning in the hallway - which makes no sense to me. One of the rooms has a portable fan & there is one other cooler in the kitchen. The AC in the hall will not cool the rooms, so in summers, you will have to open the windows. We all know what that means in Venice - mosquitoes! Make sure to carry a repellent, there was none available at the apartment.
Rooms are big enough, so are the washrooms. Kitchen is fully equipped. You need to clear your trash before leaving - that is somewhat a turn down. There is obviously no cleaning done during your stay, since the entire process of check in to check out is contactless.
Overall, highly recommended. It's a steal deal if you wish to stay close to Piazza Roma!
