This is a very comfortable apartment that is brand new. It has ample storage for all your belongings. Laundry machine is very convenient for longer stays. Kitchen is functional for making breakfast and coffee etc. We were a family of 4 who stayed here for 7 days and enjoyed it a lot.
The location is excellent. It is in a quiet alley close to the Galata tower. There are small restaurants, bakeries and cafés right around the corner. As well as many small boutiques and stores in the surrounding neighbourhood.
VNG properties are very responsive on WhatsApp and helped with any questions during the stay.
One note is the area is quite hilly. So it is a challenge to walk around if you are not mobile. My elderly parents struggled a bit. And unfortunately you can't rely on taxis in Istanbul because they're horrible. That's not the property's fault though.
