We copy the positive aspects of the other reviews: really conveniently located. Don‘t let you put off from the old entrance hall.
We arrived late in the evening. There weren‘t enough private water taxi available. Rachele helped guiding us safe to the city center. We took a cab for 40€ to the Piazzale Roma and then went with the public vapretto boat to the Mercato Rialto stop. There, Nicola was waiting for us.
