I do not have a basis for comparison with other hotels in Istanbul but based on numerous stays at four and five star hotels for business in other cities I do not consider this hotel five star. The rooms are small (but adequate). The TV has many chanels but is small (14''). The front desk staff are friendly and fairly... more

We were a group of 25 persons staying for 10 nights and using the hotel facilities for an internal company training (2-3 meeting rooms, daily meeting package including coffee breaks and lunch). We were told that it's a 5 star hotel but you can immediately see that it is a 3 stars. Lobby is big with good daylight, meeting space... more

The hotel was satisfactory, with a terrific breakfast buffet and a good view from some of the rooms, but nothing extraordinary. But they get top marks becuase I had a tight late flight, and they let me stay late in the room, and then, when I had left important documents in the room, not only found them but sent them... more

Outstanding exercise room. Very nice location. Very good for business travelers! more

Stayed at Dedeman hotel in April 2007 for business and I liked it a lot, the only downside was the cigarette smell in my first room. It was like walking into an ashtray, so I had it changed, which was done without any problems. The staff is friendly and professional and the food at the hotel restaurant was very good!... more

We spent a week at the Dedeman on business and have few complaints. Our room was large and comfortable, and the staff was uniformly excellent. The public spaces have been updated recently and are very nice. Though clean and comfortable, our room could have used updating as well. The carpet and furnishings were showing their age, and hopefully will be... more

Five stars probably have a different meaning in Turkey than elsewhere. Anyway, the hotel was just as expected: good, clean and functional for the business traveller. Very far away from historic sites but not far from the best shopping malls in Istanbul. Good value for money, with exception of food & beverages which are expensive. I recommend it if you... more

I wish the standards were higher at Hotel Dedeman. It is a typical business hotel. If you are mainly on a business trip and if you do not need to spend much time at historical sites, and this hotel is acceptable. With newly-opened shopping centers ( Cevahir and Kanyon) and entertainment places few kilometers from the hotel, it is also... more

I have stayed here a few times on business. It is semi-acceptable on that basis (close to the motorway & main banking district), but not recommended for anyone on holiday as miles away from the main tourist sights. The room was okay, but aircon not very effective. Very hot at night. Dinner poor. The restuarant is dark with annoying piano... more
