The location is 10/10. We were able to walk everywhere we needed to. Its about 5-10mins away walking from Istiklal Caddesi which is one of the busiest streets in Istanbul, and its a few minutes away from the Galata Tower. It feels like this place should be way more expensive!
The Airbnb is located in a pretty cool suburb, a lot of nice little cafes in the area. And just up the hill from the main road if you need to get a taxi anywhere.
The room itself is small and simple but has everything you need. Best for singles or couples who are planning to be out exploring most of the time. Would definitely be back!
