My girlfriend and I stayed at İlayda's place for 2 nights, and really enjoyed it. The apartment is very close to the main walking street (İstiklal street), but still in a nice and calm area, with some cozy bars and cafes around.
The room was very nice and cozy. There are also 2 amazingly cute cats living in the apartment. İlayda and Murat are also really nice hosts, so I would definitely stay with them again.
