The "apartment" is more like a suite in a hotel. There is a huge terrace with an "ok" view (you are actually surrouded by other buildings but you can also enjoy Taksim rooftops so it is pretty cool anyway).
You are at the last floor and this means you will hear a lot the Mosquee singing at 06:00 am. But probably this is an issue common to all this area. If you shut the windows properly you can reduce a lot the noise and ear plugs will do the rest.
The room is pretty big and also comfortable. Also the bed is very big. The shower is clean and wide.
When we arrived we were missing some towels and blankets but the host was very reactive and solved the issue right away.
One thing for me to be changed are the curtains. The apartment has a lot of windows and this is in general something I appreciate but when is night time is almost impossible to avoid completely other apartments to sneak inside if they want ...so you better be careful what you do if you do not like to be peeped.
Other positive point was the Internet connection. We both work from home and I can tell it was very fast and this is rare in Istanbul.
So far is an apparment I would recommend for a short stay and if you are not too bothered by Mosquee singing.
