the owner is some company and they are very good at responding and take care of issues. support is amazing. so i would not like to say anything bad about the property.
but unfortunately when i stayed there, people on the second floor of the apartment was very loud and making noise until late night and i couldn’t sleep. so i complained to the owner and they were less noisy next night, thanks to the support of the owner. but it was kinda same situation in third night. and i gave up. so if someone is very sensitive to the noise, i would not recommend. but noise in general is common problem in istanbul. i stayed at 4 apartments in istanbul and 3 out of 4 had structural problems of the building regarding noise.
