Ilhan is a very nice and attentive host. The location is good - you will be close to Isticlal street, Taksim square and Galata tower. Everything is pretty close to the description, but there are some things to expect:
* It's a basement, so no mobile connection here. Wi-fi is pretty good, but it is regularly getting disconnected.
* The shower is leaking, so you'll need to wipe a puddle every time.
* The soundproofing is very poor, so sometimes you'll hear everything from the corridor pretty loud.
* I stayed here for one week and saw cockroaches twice
