The host wasn't very polite and it was hard to reach him, didn't respond to messages at all. The place itself was pretty dirty and had a very bad smell of mould coming from the bathroom. The neighbourhood was good from the point of view of proximity to the popular attractions, like the blue mosque, but it's much dirtier than other regions of Istanbul. I recommend staying in Taksim or Kadıkoy/Üsküdar, it's cleaner and cheaper there.
