We had a lovely stay at the apartment, the location is incredible if you're visiting Istanbul for the first time! The blue mosque is a 5 min walk away, and the Grand Bazaar is a 10 min walk. The apartment accommodated 3 people well and we had no major issues during our stay. There was a loud Turkish broadcast announcement from a building next door in the morning, but if you're out of the house early, this isn't a problem. Cem was especially helpful and responsive throughout, couldn't recommend both hosts enough!
