We only used it as sleeping place and to get some included breakfast, or else we spent most of the day in London out and about. For just that reason it was a good a enough place.
According to what they say they have on hostle worlds webpage it doesn't live up to that, there is no breakfast, wifi doesn't work properly & the bathrooms are something taken out of a horror movie!! The staff is friendly but only one person speaks English, so if u need to have something done u will do it early on the day! The lack of AC made the stay even worse! The owner of this brach and hotel is just trying to make fast money. Pay a little more to get the better experience is my advice!!
It was a great stay though the door to the all girls room could have been fixed. Nice place, great location and breakfast could have been better but loved that you had watermelon! The evening BQQ was good though a little bit pricy. Very central and loved that you could walk everywhere from there!!!! Overall loved it there and if I drop by Istanbul again I will definatly check in again.
