I highly recommend LTL Beijing!
I was at the ltl language school in Beijing for two weeks and it was great! The classes were both intensive and fun, the teachers good and motivated, and after class, they offered some interesting activities. Almost everything went smoothly and if it didn’t, the super nice and helpful staff solved the problem very very quickly. So there was nothing to worry about and I was able to just enjoy my time there and focus on exploring the city and studying. The location of the school is also great for having lunch nearby after school and then doing some sightseeing.
