Looking for Native English Teacher Private Lessons

I am looking for a native English experienced teacher (preferably American accent) that can give my 6yo twins private lessons.

The schedule would be Thursdays and Fridays from 4.45pm to 6pm. The location is Sant Gervasi, next to Plaza Bonanova.

The twins are native speakers too, so looking for a teacher to help them with phonics and learn to read.

Thank you!
