I stayed there with my family (wife and kids). Tugba and Aytac very friendly and helpfull. All were done as planned and described in the site. The flat was clean and cozy and placed in historical place. The building is secured by door lock system, neighboors are quite. The bus can take you to Eminonu (tram metro) from Balat station.A lot of restraunts around. I recommend this flat.
Thank you Tugba and Aytac for all of these!
