Amazing location. Walkable to everything you want to see for the most part. Even you can walk 30-40 min across the bridge to the old town to see Hagia sophia etc.
Apartment itself was pretty clean. Kitchen has everything you need. It's not too loud outside either. There's people walking around outside but after 10-11pm it's quiet.
Only issue is with the shower. There's no shelf in the shower to hold your shampoo and soap. Also there's no door or curtain on the shower so water splashes on the bathroom floor and gets wet. There's no bathroom vent either so you need to keep the door open to get the humidity out. If these two things can be fixed it would be perfect.
