We were here for 4 nights.
Pros - 10 mins walk to famous Istiklal street. 20 mins walk to Taksim Square. 2 mins walk to 2-3 grocery stores. Many kitchen utilities. 5 mins walk to bus stop. Caretaker Ms Hildiz was very polite and welcoming.
Cons - 5 mins walk to bus stop is super steep and specially difficult to walk with luggage. Too many stairs. Continuous Bad smell in the washroom. Common washing machine is in another room. Host is friendly and good in communication but they could not make taxi reservation available for us to Airport and we had to over spend because taxi drivers in Istanbul don't go by meter.
