The Marmara Taksim Hotel, right in Taksim Square, is a modern high-rise offering splendid views of Istanbul's Old City, Beyoğlu and the Bosphorus from its upper floors.
Its rooftop restaurant, Reika, has what may be the most spectacular panoramic views in Istanbul:
Groups and conventions often fill its 432 guest rooms. If you like a very central location in the midst of the bustle, this is it.
If you'd like to be out of the bustle but still only one long block away from Taksim, look at the Divan Istanbul Hotel, the Ceylan Intercontinental, the Grand Hyatt, and the Istanbul Hilton.
