Aslan apartment is conveniently located in Sultanahmet district of Istanbul, allowing us to walk to everything in 10 mins. Apartment itself is very clean and cozy. We never met Gulnur in person, only spoke to her on the phone. The lady who checked us in did not speak English, but we were able to figure it out with ease. Information packet was definitely helpful! It's a walk up to the penthouse, so be prepared!!! And I highly recommend taking the taxi service Aslan Apt provides from the airport, it is worth it. I will definitely stay in Aslan apartment again when I come back to Istanbul. :)
