Yusuf's place is in a fantastic location, just 10mins away from the main tourist sites, tram stop and Grand Bazaar. There are many restaurants nearby too. The hosts are responsive to messages. They helped us with airport transfers and we asked for extra pillows which they provided without any issues. There is always someone in the office until late, our flight was delayed and we didnt arrive until 8.30pm, but we were greeted by the hosts which was nice.
Some things to note: there are a lot of stairs in the building and it's located at the bottom of a hill, so if you struggle with mobility then it might not be suitable. Also, it is not clearly sign posted but the restaurant downstairs, Mivan are always happy to help.
