Everything was ok.
Apartments are clean and comfortable. We lived at 2nd floor in 2 room apartments. Staff, Ali, was friendly and answered for all our questions.
Barbaros, owner of the apartments, has good restaurant, in 5 minutes walking from the apts.
Good equipped kitchen in apts: you can cook if you want.
Location is good, 10 minutes walk to Grand Bazaar and Tram line station, 20 minutes walk to the Aya-Sofia and Blue Mosque.
1 cons: poor soundproofing.
I recommend those apartments.
