Any good hotel near the Pera Museum in Istanbul?

I am going to Istanbul next month. Beside business meetings I would like to see some other things there but, if possible, without any hassle and wasting of time on traveling around. Does anyone know if there is any good hotel near the Pera Museum in Istanbul? It would be a perfect location for me.

I can recommend The Marmara Pera. It is a four star hotel located downtown Pera District. It is a minute away from business and financial centers as well as entertaining, art and shopping areas like Istiklal Street. Night clubs, historical buildings and museums are right there. The hotel is 22km away from Istanbul Ataturk International Airport.
