Hotel Hilton Istanbul Kozyatagi (Istanbul, Turkey)

A highlight of many visitors, the high standard and ludicrously wide selection of hot and cold options will set you up perfectly for the day.

Fitness fanatics are blown-away by the amenities on offer to assist with an exercise regime. Even regular gym-users will be impressed by the array of state-of-the-art cardiovascular equipment and free-weights, while traditionalists love the beautiful jogging paths to be found in the vicinity.

According to reviewers, those travelling to the Asian district of Istanbul couldn't be better located. Close to the airport and minutes from the metro, you are surrounded by shops, restaurants and cafes in one of the cleanest, calmest and safest parts of the city.

Numerous reviews suggest that the most persistent issue facing guests is the hotel's lack of bilingual staff. While managers seemingly have a reasonable command of English, the majority of lower-level staff struggle with basic communication, leading to some frustrating errors with room requests, food orders and billing.

Occasionally, a review expresses disappointment at a less than perfect customer-service experience. Staff congregating to smoke and chat or personnel using guest facilities has annoyed some, while laboured responses to requests and male attendants in female changing facilities (and vice versa) has perplexed others.
