This apartment is very clean and have everything we might need.
It's situated only 5 minutes from taksim metro and it's at the same distance to Istiklal street with all the stores, bars and restaurants.
The spot is calm, safe and quiet.
In front of the building there's some construction going on, and works (and noise) starts from 9 or 10 am. For us didn't make a difference since we waked early and we're out all day :)
Also, there's construction works all over the city :) so it's hard to be too far from one of them :)
Safa was a really good host. He arranged our delayed check in (our plane arrived later than predicted) and was very helpful printing us our boarding passes to our flights back home.
We was always available at a distance from a message.
We totally recommend Safa's apartments.
