The faculty were all rather nice to the students, and since it wasn't in a university, the 50 or so international students were a pretty tightly-knit group of people. They pushed a lot to finish the Ph.D. in 3/3.5 years, which is nice. Having so many experts in a specific scientific discipline concentrated in one place is pretty impressive, too.
My heart was elsewhere the whole time, so I'm not the best person to ask :P Germany itself was enjoyable, and I've met some fairly friendly Germans in WGs. It rains a lot in some places. YMMV, good luck!
