What can I add that others haven't?!?!? If Dodo's space is available, Grab it! you won't regret it! Everything about the location is fantastic, as mentioned in the listing and by others.
Something really special is that after meeting us for check-in, Dodo gave me a leisurely tour of the neighborhood pointing out the best places to eat and stop at. Most of this information is included in the comprehensive, personally-written guidebooks he emails to you via PDF, but a walk around put everything in very helpful context. The walk and the guides were a lifesaver for making sure we didn't end up eating at over-priced tourist traps.
Dodo also coordinated transfer from and to the airport using a very reliable, and reasonably priced service. There were a few other super helpful things he helped with, so don't hesitate to ask. I'm confident he'll point you in the right direction.
We would absolutely stay in one of Dodo's apartments again if (when?!?!) we are fortunate enough to return to beautiful and crazy Istanbul!
Thanks, Doruk!!
