Gurubish is the perfect host. She's polite and friendly, she immediately answers all questions and gives you a list of recommendations (to have breakfast or diner, to buy turkish delight etc.).
This apartment is located in a quiet place. There are a lot of grocery stores and local cafes where you can dine in or take away. It's a good place if you want to go sightseeing. For example, it takes like 5 min to get to Istiklal Caddesi or around 15 min to Taksim Square. Also there is a bus stop near the house so you can get everywhere you want to. We bought Istanbulkart at the metro station so we travelled using only public transport.
The apartment was very clean, cozy and well equipped (iron, hairdryer, fridge, washing machine, towels, two kettles, frying pans, cutlery, nice dishes, wine glasses). There is also a tiny balcony but the weather was cold so we didn't spend much time there.
We had a great time living here!
