I will go back
One important thing about the Istanbul Hilton is the availability of a Tourist Information Office (just outside the hotel). Another thing that i found very good is the availability of a trkish Hammam in the hotel's health club. It serves women from 7am to 3pm and men fm 3pm to 11pm. The amazing thing is being very clean and charging the same amount as the famous historical hammams near to Aya Sofia. The view from the room was just amazing. Their breakfast restaurant is great. and the staff are over friendly (i didn't like the reception staff though). One more thing, it's on Taksim street, within 5 minutes walk from Taksim Sq where you can find the main bus stop of Istanbul & Taksim underground station. I found internet in the hotel very expensive (7 new TL for one hour)
