The host was very accommodating. We were even moved to one of the bigger appartments that Guner and Guven have in the neighbouring building. Do not feel spooked if the street seems a little big dodgy when you arrive. People in the area seem very friendly, and you have everything you need at your doorstep. We went to the neighbourhood market on our sunday in Istanbul which was really fantastic for picking up lovely fresh food. The appartment is perfectly located for exploring Beyoglu. Just remember to bring good shoes if you are planning to walk all over. Excellent value.
