This place is not too difficult to access, as long as you are prepared for hills, both up and down, which is just the reality of the neighbourhood. We actually found the little lane that it was located on very convenient to access. We arrived by HavaIst bus from the airport to Taksim Square and then walked 20 minutes down Istiqlal Street to the apartment, which was all part of the fun of arriving in a new place. We found the apartment to be fairly quiet considering it's proximity to the hub bub, and yet very convenient to walk out the door and instantly be in the midst of it all within 2 minutes. The host let us check in quite late- when we arrived at around 11pm, someone was waiting at the door to open up the apartment for us. Physical state of the apartment was more run down than anticipated, but acceptable. Not a lot of provisions in the apartment so expect to buy your own basics.
