The view is a very very good view. when i say good believe me it is awesome. your are right on the Bosporus and one of the best spot of it . the 2 people dining area makes it perfect for watching outside. the windows are large so there is no obstruction . So 90 % this stay is about the VIEW and you get it , rest is details ....
kitchen and bathroom tools are sufficient .
house is old probably built before 2000 may be 1980 most furniture and decoration looks original may be 20 years old. so if you are into all new and modern you may not find them here.
bedroom : only one bedroom there is and the bed is full size not queen . so you may not feel so comfy ( the room is small - so queen may not fit )
the only 2 problems i would suggest to the owner is keep the bed in better hygiene condition ( you may wanna replace and use water resistant liner) ---- the second problem is heating - since it is centrally heated you may wanna put a small room heater - it is a easy fix.
so over all i gave a 5 star and the host has been great . i ma looking fwd to rent from him again . great value to Airbnb world 👍
