I highly recommend this hotel. walking distance to all the major attractions. The staff were great, really helpful re all the attractions (probably the best staff for a hotel in this price range I've seen in years, a testament to the owners). Rooms were cumfy. our room did look out at a wall but wasn't such a biggy as it meant we spent more time out and about. There is a great rooftop terrace above the breakfast room with views of the sea and city.
I will stay here again next time I'm in Istanbul for sure.
