No frills; a good place to rest your weary head - which is all we did. (Overpriced for what it is, at least when booked online.)
Be warned: it's tucked away round a corner at the end of a blind alley. We did find it in the pitch dark, but it took a while. Consider taking up the offer of an airport transfer if you're coming by air!
Our room had a mini-kitchen, but no kettle. The shower was good, the toilet was very low to the floor.
No view, but you're a pedestrian crossing away from the Bosphorus so go out and enjoy it!
We chose this place on the basis of its location, which is very handy for the sea bus port at Kabatas and not much else. (Although it is very close to the Findikli tram stop too, and a short but steep uphill walk to Taksim.)
Not much English is spoken, as far as I could work out.
