The Conrad is better location wise (Beside Yildiz Park/Besiktas) and the Bosphorus view. The Hilton Bomonti has probably the best executive lounge in Europe across the Hilton brand. Indoor facilities (Spa&Gym&Pool) also better than the Conrad.
The Hilton Bosphorus has a very nice garden and open pool. It was the first 5-Star chain property in Istanbul and has a lot of nostalgia for locals. But it is also dated. In the summer could be considered for the location, pool, views (rooms with balcony) and the garden. The executive lounge has nice views but does not compare in terms of offerings with the Hilton Bomonti.
