Translation of hinterhältig

Thanks a lot. Let's meet. Where are you located? OK, do you want to meet there? Basically, June 4 and further would be good for me. But I am flexible. I never have too many things to do in the weekend.
I slept in the jungle lodge. Dinner was really nice as there was only one restaurant were everybody gathered. My newly acquired friends invited me to join them for dinner and we had a great time.
Sorry for bothering you with so many questions. You are going to be my first online language course. The more I trust you and your website, the more I will use it and recommend it...No problem...
