My friend and I stayed in Ayla's flat for 4 nights, and couldn't have been happier with our stay. The location is unbeatable (a quick walk from Istiklal Street and down to Galata - cute cafes and restaurants everywhere) and the accommodation is simple yet totally sufficient for a home-base at night. Ayla was available if we had any questions, and was flexible about our check in and check out times. Would definitely stay with Ayla again if I visit Istanbul in the future! Thanks Ayla!
