My teens and I spent a nice week in Tayfun's place. It was clean, quiet (other than the call to prayers which we thought sounded lovely) and comfortable for an older building. We appreciated the kindness and treats from the "grandma" who lives downstairs as well as allowing us to check in early. We had some issues with the internet signal not reaching the bedroom well. My kids were camped out in the living room where the internet was fine and I preferred to get some work done in my bedroom. Tayfun worked hard to get the matter resolved the best he could. The walls are thick and he had a new wifi router and a wifi extender installed. The apartment is on a hill (Istanbul is very hilly) and up two flights of narrow stairs so be aware if you have a big, heavy suitcase like we have as we're full-time travelers. Thanks for the lovely hospitality Tayfun and our temporary Turkish grandma!
