My Vacation to Colan

I´m cheking checking in at the airport for my trip to Colan. It´s in Piura, Peru. My suitcase isn´t heave heavy, so I don´t have problems in the airport. There are many Hotels, but I stay in my aunt´s house [ instead ]. The North Northern food is good, I can eat saltado al chabelo or ceviche. The weather is good [ as well ], It´s always sunny and hot there. You should use a t-shirt and sandals. While visiting Colan, I can swin on swim at the beach. Piura is an interesting place for know [ to explore ].

I capitalize "V" in vacation because, in English we usually capitalize the words in a title (but we do not capitalize "to", "and", "but" etc.)

"The Northern food" = "The food from the North"

Overall you did very well. One more thing I would point out, is you are using an accent ´ instead of an apostrophe ' . You are writing "my aunt´s house" instead of "my aunt's house".
