We went to this bar even though we were not staying there. We took the vaporetto across to Guidecca- about 5 minute ride. Walked for about another 7 minuted and entered the beautiful Hilton hotel. Went up to the bar and sat down, slowly taking in the beautiful views. We only had time to have 2 cocktails- quite pricey but very well done. The hotel shuttle brought us back to Zattere for free. It was a great way to end our day. I can imagine that going there for sunset must be even better.
