The property is in an old building but refurbished, rooms adorable, toiletry smells delicious, complementary fruit bowl, and lots of bottled water and nesspreso/tea. The area is fancy and the people attending the bar and restaurant are pretty people. Staff could be nicer & of service for the price you are paying, seems like they are tired or mad. I booked through expedia and since I am a Gold member, I could have an upgrade if available. It was available but they wanted to charge me 150€ per night for upgrade (i stayed 3 nights), the offer in internet was also stay 3 nights in Bebek and get complementary massage in Nisantasi, but it wasn’t respected either. They ended up saying I needed to stay in Nisantasi. Restaurant, waiters could be more attentive & better attitude: 40usd for Caesar salad with chicken & Pellergrino. Bar (roof top) great DJS, great music, beautiful view of the Bosphorus, upscale visitors & celebrities, waiters attentive if not too crowded, otherwise if your not a regular, you will be served last. So I am giving 4 stars even though I could have give them 3, but since it was fancy, pretty rooms, and great location, I give 4.
