Nice please overall, but there are some moments to consider:
1. No sound isolation at all, you hear everything everywhere, and others who’ll hear you phone’s vibration.
2. Housekeeping is not daily, whey can’t not clean it at all if you don’t ask.
3. No kettle in the room.
4. None of the windows in my room could close properly, so it was a little bit drafty.
BUT:
1. The location is very convenient to explore Istanbul.
2. Lots of shops and cafes of all kind nearby.
3. You can get to both airports by public transport, I did it twice, it’s a long trip, but comfortable enough.
4. Wi-Fi speed is workable, about 1Mb/s.
So I’d rather recommend it
