Evrim our host host was great. His place, which is an old private house that he has refurbished is wonderful. The location was perfect. just across the small alley from the famous Catholic Church St. Anthony of Padua (in Turkish Sent Antuan Kilisesi) . Good to know to tell Taxi driver. His house is a 3 minute walk from Istikal Street, down the hill towards the Bosphorus. We rented the 2 bedroom family room with kitchenette and private bathroom. It is located on the ground floor. For cost, location and comfort I would say it would be hard to beat Avrim's house in Beyoglu.
