We both had a great time here in Xela! I definitely recommend the one-on-one Spanish classes in Xela for improving your fluency, and I can speak about studying exclusively Spanish at either Pop Wuj or Proyecto Linguistico Quetzalteco. For a medical school rotation, Pop Wuj was a great balance of intensive Spanish with plenty of good clinical exposure. We were very busy! February is a beautiful time to come to Xela- the weather is perfect for taking advantage of hiking and the lake. Overall a highly recommended experience. Feel free to get our email through the OIA if you have more questions, either of us would be happy to talk about the experience in more detail.
