Pi was extremely helpful in providing directions early before I arrive. The apartment is gorgeous, so are her cats, though I'm have to be always extra careful when i open my bedroom door so that they don't dash into my room. That said, all her three cats are very well behaved and pretty.
Apartment has everything a traveller needs, I can even take a piece of banana in her kitchen before I start m day. Her bathroom is very well equipped. Bedroom is spacious, bed is so comfortable and smells nice.
Location wise, it is 10mins to taksim or tophane station, so it's really convenient. There is a cafe called susam cafe below her apartment, which serves up quite nice food though a tad expensive.
I stayed for only 3 days in her apartment, so I didn't had the chance to talk to Pi much, but really appreciated her advice and tips.
