Cesim is a very nice and friendly host. Overall OK place. It is close to the Blue Mosque area.
It is actually 2 separate apartments. We were looking for 1 apartment with 2 bedrooms since we have kids. However, it was not mentioned in the description. The door of one of the apartments was missing a proper handle/knob. it was very hard to get out from inside. Kids could not open the door. It was a safety hazard. It was fixed after 5 days.
Keep in mind you will have a steep walk uphill to get there or any of the attractions including the public transportation.
The place was not ready when we were checking in around 2 PM. It was still getting cleaned. It was inconvenient to deal with after almost 16 hours of flight and the associated commute time.
WiFi is very unreliable. It always didn't work in the morning and eventually stopped working altogether. Not having a properly working WiFi was really inconvenient. We ended up using the roaming data plan on our mobile.
One of the pillowcases when we checked in heavily smelt of sweat; probably wasn't replaced. The bed sheets were smaller than the bed itself. They were fixed later on.
The laundered clothes came back very damp in the bag. Beware of it if you are going to use the laundry service
