Very good location - near to Camberlitas tram stop, Blue Mosque, Hagia Sophia and Topkapi Palace. You can choose to walk or to take tram around Istanbul. Not far from the hotel, you can just walk to nice restaurants. Supermarkets and shops are also nearby.
As for the room, it offers everything that you need - clean bathroom, kitchen, fridge, wifi etc. The bed and sofa bed are really comfortable.
The staff at Cube Suites are all very cheerful and helpful. They helped us to arrange transport to/from airport and also booked the ground tour for us. Very easy to check in and check out of this place. Surely will come back and will stay here again. Love from Malaysia!
