I had a great experience at Suphi's place, it is centrally located to Taksim Square (the heart of Istanbul) and to the metro for easy access to everywhere in the city. Suphi was helpful and easy to communicate with and did a lot of little extras to help me out (early check in, advice on the area, called me a cab etc). Suphis goes above and beyond to make sure that you have a great stay and he is helpful, friendly and nice and was available to help me at all times. I would stay again and I highly recommend Suphis place if you are staying in Istanbul for business or pleasure. I would stay again.
