Mehmet is a kind, supportive, available and responsible person. Check-in was flexible. Her colleague, Zeynab, is a positive and supportive lady too. The location is perfect, close to the Metro and bus station. The Sisli area is quite safe, with access to shopping stores. The flat was clean and comfortable. The heating system works properly. All in all, I enjoyed very much staying there for a week, and if I travel to Istanbul again, I will choose the accommodation again.
