I'm a medical student who will be spending 6-8 weeks in Guatemala City working on a research project at a clinic. I have gone to language schools in Xela and San Pedro on different occasions and two years ago I spent several weeks in Guatemala City at this same clinic so I know the lay of the land generally. This time I'm looking for private afternoon/evening Spanish classes. Does anyone know of a language school or tutor they could recommend in the city? Thanks in advance!
