Convenient location by the Rialto Bridge. The directions indicate taking Vaporetto "Line 2" to get off at Rialto bridge, but "Line 1" (Rialto Mercato stop, though slower) is more convenient to get off the same side as the apartment since its difficult to haul luggage over the bridge.
Check-in was easy with someone waiting at the appointed time. It was more like a managed space with minimal decor if any, than a homely one. There's a restaurant right under the apartment, so it was quite noisy until 1-2am. The first day we found it hard to fall asleep but then with all the walking in Venice, it was manageable the other nights. Overall, it was quite comfortable.
