Omar and Aysha had a very clean, warm and well equipped apartment. This apartment is actually even better than its photos. It's spacious, beds are comfortable and water is always warm for a relaxing shower. Although it's a large apartment, but its heating system is good and it's not cold during winter. Aysha and Omar are responsive hosts and they try their best to make you feel at home. We only had one negative experience, that was due to a prolonged power outage, but that wasn't really Omar or Aysha's fault. It's also far from the historic sites of Istanbul.
All in all, I recommend this place to everyone mainly because the house is well equipped and the hosts are great.
