Clean room, effective AC (although the condensation drip bucket overfilled the first night), local/italian-style breakfast (espresso and forgettable junk food). Good restaurant recommendations from a very friendly host.
Host is prompt with communication, which helped us to make other plans for our bags (he will not hold them until check in; it's more like an airbnb style arrangement). The train station, maritime museum, or private company can hold your bags until check in.
Housekeeping services rooms in the 3-5pm time frame, which makes an afternoon break from the heat a bit more complicated. It also results in the 6:30pm check in time. This is a fair exchange for the excellent value of the room (location, price, clean/modern room, comfortable bed).
I can't remember if our host told us where to go once inside the building; another guest let us in and told us which floor to take the elevator to. However, we could have just as easily texted the host. There is no reception / etc. - the BnB is inside an unmarked room inside one room of the multistory building. Just ask the host for directions.
