Perfect location, low-budget but cosy, extremely friendly Nasri :)
The apartment is just as in the photos. A perfect place to stay for several days for this price. Quiet, strong wi-fi, nice projector to watch old movies after walking in the Istanbul touristic center.
A bit cold (we stayed in February), but there was 3 heaters, so it was not a big deal. Think it is a great advantage if you come in summer.
