If this apartment is available, book it!
First, the location can’t be beat. You are an easy walk to St Marks Square but far enough away that the crowds are not a problem.
Second, the quality is terrific. The place was recently renovated and is in great shape. The bathrooms and kitchen are great. The AC, which covers the apartment from two locations, was so helpful for our summertime visit.
Third, the hosts are lovely. We needed help getting in twice and both times they were there within five minutes. They had great advice. They helped arrange all the water taxis we needed.
