I would not hesitate to recommend Aslan Apartments and would happily stay there again if I return to Istanbul. Good location in a primarily residential area – away from the touristy hubbub but still only around 10 minutes on foot from the Hippodrome, Blue Mosque, Aya Sofia, and (in another direction) Cemberlitas tram stop. The area was quiet and safe – we were two girls, often returning to the apartment towards midnight, and at no time did we feel unsafe.
The apartment was clean and comfortable, had everything that we needed, and everything that we used worked. Gulnur and Aslan were extremely responsive and helpful, both before and during our trip, not only providing information about the apartment, but also tips and recommendations while we were preparing our trip.
Two points to note: (1) There is no lift in the building and (2) there are no curtains on the front windows of the terrace room/second bedroom. These did not pose a problem for us, but are simply points to be aware of.
All in all, this was an ideal home away from home. Teşekkür ederim, Gulnur and Aslan!
