Mert is a great host. He is always there when you need him and his Apartment is also great located and in the best area of Istanbul Osmanybey/Nisantasi. The Metro Station is near to the apartment so that you can reach sightseeing places quickly with the metro. I highly recommend the apartment of Mert and would really like to stay at Merts apartment again. As i already said he is a great host, always there in need and really friendly and kind.
