We had a wonderful stay during our visit to Istanbul. The location is very near Taksim square; besides grocery shops are located very near to the apartment. There is a beautiful rooftop in the apartment. The kitchen was good with everything needed to prepare dishes by yourself. Despite there is a possibility to place more people to the apartment on Airbnb in my opinion is good to consider the quantity basing on availability of 4 queen size beds.
It is also important to consider that one toilet/shower and one "room" is located on the rooftop level.
We also had some troubles with one of the keys to enter the apartment. It is better to repair it, because only me among 7 friends that stayed was able to/understood how to open the door.
But despite few minuses I may recommend this apartment for stay.
