We stayed there for 2 nights. The location of the apartment is very good - it's close to Istiklal Avenue (approximately 5 mins walk) but nevertheless it wasn't very noisy. If you are after a basic and budget apartment in Istanbul and want just a simple place to sleep then it might be a good option. But if you are going to spend more time in an apartment and need good/fast Internet then you might consider another option. Overall it was what we wanted and worked perfectly for us as it was close to places we wanted to visit and to our friends' places. Also Volkan was prompt, helpful and friendly.
