We LOVED Ulpan Or! We did four weeks this summer and learned a tremendous amount of Hebrew. (It was hard work, but we really enjoyed it.) The teachers, the materials, everybody and everything there was great! I'm now doing GDL online lessons back in the US, and I can't wait to come back to Jerusalem for more in-person learning. The one thing I would add that is not obvious is that, while Ulpan Or may seem to be more expensive on a per-week basis, it is actually much less expensive on a per-unit-of-learning basis than a traditional ulpan class, because you can progress so much faster (if you do the work), We can't recommend Ulpan Or strongly enough.
