This is the original deluxe hotel in Istanbul so it is set among spacious grounds. There are five restaurants, three of which operate year round. It lists tennis courts, the largest swimming pool in the city and fitness centre as some of its line up. It really contains everything you'd expect from a five star hotel.
Try and get a Bosphorus facing room as the views are simply stunning (see photo). If you can't, then soak up the same views from 'The Terrace' restaurant while having a drink.
There is nothing that sets it apart from any other deluxe hotel, but it has everything you need, and the staff are all polite and very willing to help.
