Birol is a great host. Communication was excellent. We connected through WhatsApp and we have everything set before we arrived Istanbul. He helped us arrange transportation from and to airport through a transportation minibus company. pick up times were accurate and prices were reasonable. The apartment is located at Beyuglo district few steps away from Galata Tower. Lots of attraction and places to see in Beyuglo. Many nearby restaurants and coffee shops to try. The apartment is very clean. Wifi is working. Three AC units with great air conditioning. The kitchen is well equipped. The istiklal street is 5 min walk away and Trolly take you to Taksim square. The tram station is 10 min downhill walk so easy if you wanna cross the bridge and go to Eminonu and golden horn area of Istanbul. The way back would be an uphill walk which I did not mind but wife did. The alternative is to use the Metro which is 5 min walk from the apartment. I would definitely rent and stay at Birol place if want to come back to Istanbul.
