This apartment is in a very good district of Istanbul and it is very beautiful, cozy, and has everything that you would need for a short stay.
However, it looks like there is a problem with coordination between the owners, the manager, and cleaning service. We asked to check in one hour earlier, and they let us do that, but it turned out that the apartment was not cleaned yet. Cleaning arrived only 2 hours later and it wasn't quite comfortable as we were working and had working calls but were forced to change location between rooms. Though the people who cleaned the apartment were extremely nice and were really sorry for the inconvenience, it wasn't their fault at all, they weren't warned that we'd already checked in. I asked the owner about the situation and she replied that the previous guests checked out later and they hadn't enough time to coordinate cleaning. I asked for later checkout as well to compensate for the inconvenience. They said that it is not a problem at all but on the day of our checkout cleaning came earlier and opened the apartment with their own key without warning. It wasn't nice.
Also, it is worth mentioning that the apartment is not well soundproofed, we heard every step of neighbors upstairs and heard everything that they watched on TV. In the bedroom, you can also hear everything from the street. If you are sensitive to noise, I will not recommend this place.
