Thank you for writing my friend, it’s always nice to hear from you. I’m very happy to hear about you and that thanks to your job you will spend three weeks in my city, which has plenty of places to see.
From what I read you will have enough time to visit and discover new places ans that´s great, because you can free your mind from work at some moments and that´s pretty important. First of all you should visit the finest restaurant in town, Don Vito, it’s Italian food, simply amazing, I´ve been there many times and the attention is wonderful, like a five stars hotel.
Secondly, make sure to visit the beach, it´s gigantic and also one of the biggest attracion of the city nowadays and if you are not afraid jump in the water I recommend you to do it, it’s a great experience.
On your free days, the best advice I can give to learn the language is talk to every person you can, go out there and expose yourself, ask questions, ask for typical phrases or words and just be brave to use them.
I hope to hear from you soon my dear friend, it´s great to know that you a growing a lot as a person and any question I’ll be here to guide you in the town.
