G Residences is a mix of both good and bad, but mostly good. I am a retired hotel executive, so you can trust my comments.
Our room... 22nd floor 333
The photo sown in the airbnb listing is from the property website, not from our window.
The room was missing items for the kitchen, so we had to call for help.
No vacuum machine, but I think that was advertise as included.
Heat was v. Good. Kitchen appliances good. Location good for grocery, taxi/uber, coffee shop.
The best thing is the helpful staff in reception. Made copies, explained, and let us stay until afternoon because our flight was delayed.
Last negative thing...the tv seems to be limited to Turkish channels. Didnt ask for tv help because I had lots of works to do anyway.
Overall stay here if you need to be in the Istanbul Mall, Yenibosna area.
