Communication with Derya is great and she is very attentive. Check-in was easy as the flat is easy to find and his brother was waiting for us. The flat is very small but it is very practical and it has everything you may need. Location is amazing, very close to transport links, shops, restaurants, and cute cafes! It is definitely a better choice staying here over the touristic area in Sultanahmet. Overall, great stay and I'd really reccommend David &Derya’s flat.
