Nicola is a perfect host! He met us at the vaporetto stop and walked us to the apartment. He is friendly, informative, and helpful. We loved the apartment, very modern and comfortable, and the area is perfect for us...it is a quiet building and neighborhood. Free of crowds of tourists, we didn't mind walking farther (30 m) to Piazza San Marco. We enjoyed the gardens and lagoon near the apartment. We have been to Venice many times and we were pleased with the tranquility of Castello. I highly recommend this place.
