Turkey Sumahan on the Water, Istanbul As a trainee architect, the daughter of the Turkish-American owners of Sumahan drew up plans to convert their old Ottoman raki distillery into a 20-room hotel. The result is contemporary and cosy: most rooms have wood-burning stoves or open fires. It is perched on the Asian side of the Bosphorus, in the village of Cengelkoy, with stupendous views across the water from every room (binoculars are provided). Since it’s a long trek into the parts of the city most visitors want to see, the hotel operates a smart motor launch, which shuttles for no charge, morning and evening, to and from the Kabatas quay in Beyoglu on the European shore.

It was overhauled in 2010, and now every room has a large balcony with a view towards the city or to Lokrum—a wooded island that contains the world’s smallest sea, the Mrtvo More (Dead Sea). There is a lift that takes guests down to a man-made beach, or to the hotel’s handsome Venetian motoscafo (water taxi), which makes 11 daily complimentary round trips across the bay to the Old Harbour.

Italy Palazzina Grassi, Venice Philippe Starck’s verging-on-surreal transformation of a 16th-century palace on the Grand Canal is a lesson on how to merge the contemporary with classic Venetian style. There are expanses of decorative bevelled mirrors, Murano chandeliers, and mask motifs on the lampshades redolent of Carnevale. The result is eccentric, romantic and glamorous—especially if you arrive from the airport in the hotel’s mahogany motor boat, built in 1962 in the Celli boatyard on Sant’Elena island in the lagoon.

Russia Grand Hotel Europe, St Petersburg Built on 101 islands and crosshatched by canals, St Petersburg is as watery as Venice. Since 2009 Orient-Express’s Grand Hotel Europe on Nevsky Prospekt has kept an elegant €180,000 speedboat, Katarina. It is moored by the nearby Anichkov bridge on the Fontanka river, and available for guests to charter in order to explore the city’s web of waterways. It’s also the fastest way to travel to the imperial palace complex at Peterhof on the Gulf of Finland, which is otherwise at least an hour away by metro or road. Doubles from 11,682 roubles (£246); boat charter from 7,000 roubles an hour); grandhoteleurope.com
Vietnam An Lam Saigon River, Ho Chi Minh City This small resort hotel, which opened last winter, is set in tropical gardens on the banks of the muddy Saigon river on the edge of the city. Most of its 15 rooms and villas have river views and some have their own pools, though there’s also a large main pool, as well as a spa. If that speaks of sloth, the hotel is an equally good base from which to explore Ho Chi Minh City, thanks to its powerboat, which whisks guests to the Bach Dang pier in the heart of District 1 in just 15 minutes.
