We entered the club which started to fill up around mid-night. The atmosphere was great and many handsome men and beautiful women were dancing on the different floors of the club. We were upstairs.
I am learning Spanish in university but I also have to improve it for private reasons. Do you have any suggestions. It is giving me a hard time lately as it is difficult. I need to be very patient.
In Bariloche it took us around 3 hours to find a nice hotel. The prices varied a lot and there were no bargains. We settled for the Hotel Tirol, owned by an Austrian lady. It was a cute place with a lake view.
