We had a comfortable time staying in Ugur's apartment, the room was exactly like the pictures. Pros is that it is clean and spacious with a big living room which makes it feel like a proper home. Ugur provides an Istanbul card which can be used for all transport, buses and trains etc which can be topped up. And in a group, you will only need one card to pay for everyone. If you are taking Havas shuttle from Istanbul ataturk airport, alight one stop before Taksim Square (point hotel) and walk 5mins to his apartment. Avoid taking taxis!
