Aysu's place is amazing for many reasons.
Aysu herself is very hospitable and warm, always in contact. She was ready to help and give advice at any time, she knows the city very well. Also she's an amazing chef and even made me a breakfast on the last day of my stay. And yes, there is also her lovely cat)
Place itself is very clean and beautifully decorated with much love. Historically painted walls and ceiling and all modern amenities at the same time – it's perfect. I could always use the kitchen and cozy living room.
The location is super cool, 2 minutes from Galata tower and 5 mins from Karakoy port, but on a quiet street, which is very rare for this area. All around are cafes and shops, vivd local life of artsy Beyoglu area and pulse of true Istanbul.
