Possibly. But just a couple thoughts to consider. Eminonu is where the spice market it, there are not too many rug sellers in that area, though I can't say there are none. There are far more rug sellers however closer to the grand bazaar, which is in another area, on the golden horn above where she was in eminonu but in the opposite direction serkeci.
Additionally it may be worth noting that rugs inTurkey are not cheap. A 3x5 all wool kilim is about 200 US dollars, a 5x8 100% silk woven rug will run you 2000 US dollars. Because even small rugs are expensive, and given that she was on a limited budget, I'd be inclined to guess she was in the market for buying a rug.
But who knows for sure.
