Pinamar and Cariló in particular are very nice to visit but very overpriced these days.
Pinamar still has some life in the winter because it’s quite a big city.
Guess you would have Mar Del Plata for everything else in wintertime.
Works well if you have a DNI and the app.
Sometimes you get a bit of a worn out bike and on occasion the bike won’t park back into the station and then it claims you haven’t returned it and can’t take out another bike.
Used them quite a bit when I lived in Capital
