Amazing apartment. Sparkling clean and on one of the most communicative spots in the city! There are bus stops in both directions 1 minute away from the location. The metro station is 3 minutes away. The last floor where we were also has some breathtaking views of the city with two balconies.
Something to keep in mind is that the building has no elevator so not too friendly for parents with a stroller.
Nevertheless, it's fair to say this has been the best apartment to stay in from our 5 visits to Istanbul so far!
