Colegio Delibes, Salamanca

Can anyone tell me if they have studied at Colegio Delibes in Salamanca and if so, what it was like. I am finding it difficult to choose which school to attend in Salamanca as they all seem to offer similar courses for similar prices. Also, for those who have studied Spanish in Spain before, can you recommend the most effective course (4 or 6 or more hours per day). Any other information regarding study in Salamanca would be a great help too!
Muchas gracias

I took a course for four hours per day (8 weeks this summer). I found that 4 hours was plenty as your mind can only absorb so much. I would tell you that of equal importance is to spend time with spanish speaking people outside the school. You will learn as much in a 1/2 hour conversation (an practice what you have learned) as you will in an entire day in class. Take advantage of being in Spain. Have fun!!!
