Blu Hotel Istanbul is right at the commercial center of the Old City peninsula. Historia Shopping Mall is just a two-minute walk, this boutique mall offers international brands (Zara, H&M), big supermarket and food court which becomes a lifesaver for any family in need of a familiar meal or groceries.
Five minutes away for history lovers is the Pertevniyal Valide Sultan Mosque. Built in a rather photogenic neo-Gothic/Ottoman style, it forms one of the most unique architectural mosques in Istanbul. Also within walking distance (10-15 minutes), there is the Fatih Mosque, a giant complex at the core of conservative Fatih district where an extremely genuine view of local religious life can be observed.
Technically yes, main tourist sites are within a "walkable" distance of about 25-30 minutes but through very busy streets. However, the Grand Bazaar (Kapalıçarşı) is much closer and can be reached within about 15-20 minutes walk up Ordu Street passing through the wholesale textile district of Laleli which in itself is an experience.
