Decent hotel with helpful staff. The rooms are basic and many weren't refurbished yet, especially on higher floors so the hotel doesn't have a 5 star feel to it. It has a business centre which is in the marketing manager's office which is a bit uncomfortable. The location is good for business definitely not great for anything else, it's on... more

I stayed in the Hotel Dedeman Istanbul for three nights in February 2009. I had a double room on the 7th floor. Starting off, the lobby staff were generally friendly. All guests need to walk through a metal detector, but they generally let you pass whether or not you set off the alarm. The room was pretty basic: bed, desk,... more

This hotel is not a 5 star hotel,considering canadian standards maybe 3 star.There are much nicer hotels for less price.It's too far from city's touristic attraction and you haave to pay around 20YTL (20 cad$) everytime you get a cab to downtown.(if you have a good taxi driver who is not trying to make the way longer). There is a... more

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 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
