Location is very good to access all the main landmarks of Istanbul.
However, communication with the host was not great, we received a template message on the day we booked but then no answer to the following 3 messages, we had to call one hour before to make sure we could still come.
The room we were given was not the one we booked (with a square bed), the room was fine but I would have liked to know the reason of the change.
There was a problem with the water which was cut for several hours in the whole building. We sent a message that remained unanswered, we had to go down to the reception desk and get a very unengaged answer about the issue. Water came back during the night.
