Everything was great, from the reservation to checkout. Hosts met us despite our late arrival.
The apartment is excellent, it is very clean, quiet and well located, shops and pharmacy are nearby, metro station in 15 min away. Gurkan and Regina are very nice people, they provide you with all information you might need about the surrounding and Istanbul itself. They even buy Istanbul card for us, which will stay for next guests. If you have any queries or questions, you are quickly answered. They organized the taxi to airport for us in 05:30 a.m.
I highly recommend this place!
