My wife and me sailed on the Nieuw Amsterdam from May 4th to May 16th 2015. We went from Venice to Istambul and back to Venice. The ship was absolutly perfect. Very comfortable and we specially appreciated that there was lot of space everywhere on the ship (ex: hot tubs, pools, restaurants. The food was very, very good at buffet, at dining room and specially at Pinnacle Grill. 2 nights with Turkish BBQ at the lido pool and again, it was perfect. Service was impeccable any where on the ship but we specially enjoyed having our first morning coffey at the Explorations Café on deck 11. In overall, the cruise was way above our expectations. We were looking for a cruise not too crowdy and we were absolutely enchanted by truise.
Venice is a real labyrinth with its narrow streets, shops, buildings and canals. Venice is a water-city as we never see anywhere else in the world. It's a must to visit in a lifetime. San Marco Place, the Rialto bridge, Murano, Burano, vaporettos, gondolas etc... are remaquable.
