I booked this for my family who traveled to Istanbul for the first time.
Enes was very nice and helpful. y family arrived very late due to flight delays and he waited for them at the airport. The apartment location is great, very close to Galata tower and with easy access to the metro. The apartment is clean, well organized and beautifully designed. It has a big TV, wifi and hot water were available all the time. Enes provided my family with all the necessary things they needed such as cleaning products, plastic bags, etc.
The only thing you should expect is that since this is underground, air circulation is not as great as one would expect but that's common in this part of the world and with a basement property.
We highly recommend Enes and his place. Would definitely come back.
