Understated luxury is the keynote here, and it's hard to believe that this century-old building was once an infamous prison. Each of the 65 rooms is classically designed with Turkish textiles and art adding eye catching details. The rooftop terrace and large, leafy courtyard are relaxing city retreats.

Everyone from Agatha Christie to Ernest Hemingway once stayed at this iconic Istanbul hotel, open since 1892. Rooms are a slice of old-world elegance, afternoon tea under the chandeliers in the lounge will transport you back in time, while the pool and spa provide ample 21st century updates.

Right on the Bosphorus Strait's shoreline and partly housed in a former Ottoman palace, the Kempinski boasts some of the most opulent rooms in Istanbul. The waterfront pool terrace offers unparalleled Bosphorus views while the bar, restaurants and spa offer plenty of opportunity to swaddle yourself in luxury.

Quirky folk art touches, Central Asian textiles as bedspreads and the odd antique give the Empress Zoe’s rooms plenty of quirky appeal. Set within a row of Ottoman era mansions, with a lush garden and a rooftop terrace with views over Sultanahmet’s Byzantine period walls, this hotel brims with character.

Sleek design and ultra-friendly service make the Ibrahim Pasha stand out in the crowded Istanbul accommodation market. Little extras such as complimentary fruit in rooms and Molton Brown toiletries in bathrooms add a luxurious feel while staff go out of their way to help guests, creating a home-from-home vibe.

A stone's throw from the Aya Sofya, this rather grand 19th century building once served as a hospital and school before being transformed into a hotel. The common areas here are full of elegant Ottoman character and the gardens and terraces provide tranquil respites from the city.

With a history dating back to the heydays of the Orient Express, this establishment has seen many writers (Hemingway being one of them), artists and actors step through its doors. Though the hotel has had many rounds of renovations over the years, the 1900s atmosphere is still very much palpable and underlined by the dark wooden interior and velvet drapes. It's also within walking distance to Taksim square, and near to many theatres and restaurants.

This family-run boutique hotel offers an old-world atmosphere trussed up with modern conveniences in an Ottoman-era mansion. The smallish rooms have polished wood floors and are classically styled while the rooftop cafe has views of both the Blue Mosque and the Sea of Marmara.

In prime position, slap in the middle of Sultanahmet's historical quarter, this family-run hotel has long been a budget traveller institution. The simple rooms are spick-and-span and decently sized and the roof top terrace (where breakfast is served) has excellent views over the old city’s domes and minaret punctured skyline.
