I have been in several Marriot properties (I am Bonvoy Gold Elite)... however the Sisli property seriously impressed me. I was there with my wife on 2 separate stays in mid-October - on both occasions, I could not help but marvel at the city scape view which stretches right upto the oceans. You can pretty much see everything, from the sunset, the Euro & Asian parts of town, the oceans & the straits. The location is also perfect - from shopping to casual walk down Istanbul walk ways. The staff were also super helpful. I left behind one piece of luggage in their store room for 7 days & then came back to collect it in the last couple of days. A much deserved 5 star rating !

Great hotel with great staff and have good atmosphere and location... The breakfast was delicious and ervething was great but one of the day i order coffee from one of the server, the server tolds me that it's ready and i can take it by myself ... So I didn't worried about that and then when am walking to my table another server he saw me and becames angry that how they allowed me to bring it by myself and he assisted me..He was really great server i would to express my special thanks for him, he called "Mr. Bulent"... He works sincerely, he was so attentive and speaks in English very well...
