Great spanish school in the new part of the city by metteks
Instituto Superior is a great place school. I studied there for two weeks then I went to Otavalo, where I also studied for two weeks at their Spanish school there. I stayed with a local family, in fact one of the teachers. It was a great experience, as they spoke Spanish all the time, and I got to see how they live and eat the local food etc.
The teachers are great, but a little old fashioned, compared to teachers here (I am a teacher myself). They write down everything they teach you on a piece of paper, and then you get to keep it, and can use it when you practice. In the coffee breaks, you can sit in a nice living room or in the garden and talk to fellow students.The school also arranges trip in the weekends. I went horse back riding to the volcano Antisana and I also went on a trip to the colonial part of Quito. They also have barbeques at night, and one time we even had meringues-lessons.
The school also offers free internet (at a nearby internet-place, maybe they have it at the school now, I don't know).
The school is located in a nice part of Quito, where it is very safe.
