We stayed at one of the istanbul place apartments called galata place. The apartment was great, clean and beautifully appointed, we shall certainly recommend it to our friends.
Istanbul was fantastic, so much history, so much to see and do, not enough time to do a fraction of what we wanted to so we shall all be back.
The people are so friendly and helpful, even the shoe shine guys who manage to catch you unawares with your feet on their little box before you know it!
Is this your business?
