I was really happy to stay in Ayşegül apartment. I was travelling alone in Istanbul but with the help of girls being welcome and friendly I never felt truly alone. They gave me good advices were to go and told me some good locations nearby.
The apartment is situated in historical building, and there is a special atmosphere inside, with high ceilings, big windows and lots of fancy details! You will find everything you need for your stay - coffee machine, kitchen stuff, hair dryer, towels.
The location is perfect, area Beyoğlu is like European city with tiny cafes and lots of antique markets. It's also nearby the Taxim square, therefore it's easy to get to any airport.
Me personal suggestion - you should definitely visit bakery "Tarihi cihangir simit firini" on the Türkgücü Caddesi street.
I will definitely recommend you to stay at this place. Ayşegül - superhost!:)
