Great place to stay in a lively hip part of Taksim. Close to the shops, excellent restaurants and lovely/cool bars. We walked to Hagia Sophia/Topkapi Palace which took 40-45mins this may sound far but in reality it went very quick and off course there are lots of things to see on the way...not least finding a cafe that sells Kaymak (Turkish Cottage Cheese with thick honey), a must for one of your breakfasts.
A great place to stay for your sojourn to Istanbul.
