A lifestyle description

Dear Amanda,
Hello, I'm Mar and I'm 12 years old. I live in Vallcarca, near the city of Barcelona. My house is quite near to the mountain. I live there with my parents and my sister, Alba.
I love my house, it's a duplex, and it's quite big.
In the first flat, there's the kitchen, the toilet, a room to study, with a computer and shelves with a lot of books. There's also the dinning room, a really big living room, with a big thin TV, two sofas, a stereo to listen to music... And in the living room, there's also a snail stair to go down.
Then, in the second flat, there's a piano, three rooms and a toilet.
When I was younger, I wanted to share room with my sister, but now if I shared room with her, I would be crazy! She doesn't tidy the room, but if she did some tidying, the room would be nice and bigger.
Well, my room, isn't as big like Alba's one, but for me it's enough. There's a big table to do homework, a big bed and a really, really big wardrobe with mirrors. The thing I like most, is my computer.
I love reading, listening to music, spending time with my family and with my friends and also playing the piano.
I haven't read Harry Potter for the moment, but my sister has, so I have all the books at home. Thankyou so much for writing me.
Lots of love,
Mar
