The owners name is Gabriel and he is wonderful!! Even came over on a Sunday to help me out with an issue! He speaks English well and is from the Belgrano area.
He will do single repairs or even has an annual contract you can do for montly maintenance and repairs.
I wouldn't hesitate to call him again for any issues!!!
