Everything is very simple and clear, all directions have signs and a printed work schedule. I came and went from here to Dalaman airport. Very convenient transfer is pleasant 210 liras. We also rode dolmusha to Turunch from here.
A cozy train station with an understandable schedule, they will tell you the information in English. Ride in comfortable buses. Be sure to visit Fethiye if you are in Marmaris!!)
Overall convenient, close to the metro. There is a paid toilet, the cleanliness of which is questionable. There are cafes and shops. The staff seemed responsive, you can figure it out.
