Gulsen was a great host and offered us a beautiful place to have our little family reunion. We were a group of 7 people...but 10 could have slept in this apartment comfortably. Being new to Istanbul we naturally had questions, and he was quick to answer them. He arranged for transportation to and from the airport for us. I work in construction in the USA and I was transfixed with how beautiful some of the elements of the apartment were. Only bad thing, He is on the 4th floor like advertised, but it is really 4-1/2 flights of stairs. the stairs are really cool...just a lot of them. They got us ready for all the uphill climbing we would do walking around the city! We plan on visiting Turkey again in 3 years...we will be looking Gulsen up for that!
