There really isn't anything bad to say about the apartment, or Ricardo and Mariana as hosts. They have an excellent setup, very easy for checkin and checkout. The apartment is clean and well equipped, with plenty of space for a family of four. The complex itself has a very nice pool, and a well equipped gym.
Be aware that the centre of Estepona is a good walk, about two miles - we like walking so it was no problem to us, and good to walk off a meal in the evening! The walking route is also very easy. However, there is plenty of parking in Estepona for people who prefer to drive. There is also Laguna Village nearby, which is a shorter walk and also has a few restaurants. All in all, a great place to stay!
