We sent to the Toro restaurant in this hotel , sincerely the worst restaurant I have been in whole Turkey. We ordered chicken and different sushi rolls. We were waiting for 1 hour for our order. Sushi were disgusting, they didn’t do it by themself, ordered them at a different place and brought it on the plate with industrial sauce. The chicken had no taste and texture like it was frozen before. I ...

We stayed for one night, had dinner at Toro Restaurant, and booked a 1-hour couple’s massage at the spa. Here’s my overall review: The spa is located on a hilltop and accessed by buggy, with a truly stunning view. However, you can’t enjoy this view from either the massage room or the relaxation area. The massage itself was average in my opinion, and the refreshments afterwards were quite underwhe...

I have now spoke to possibly...

Six Senses Kocatas Mansions Istanbul was an absolute catastrophe for our New Year’s Eve stay, where we paid 2000 euros per night only to endure shockingly poor service, utterly unprepared staff with dismissive attitudes, and zero planning from start to finish. The gala at SAX was a freezing disaster—guests shivering in jackets indoors due to the biting December cold, with no heaters or setup despi...
