Hi everyone!

This is my first post in this forum.
Firstable I'm saying that I'm trying to improve my English by myself. At the moment I'm using a book which is aimed to students to achieve level B2. There's a exercise which asks me to write a letter for your friend who's looking for a house to rent.
It's my letter:
Dear Laura,
How is it going? Hopefully fine. You asked me to find a house for you and I think that I've found the right one.
Like you said you wanted a house in the countryside. The house which I found is located in a quiet area, but it’s also near the city so you don’t have to look for a new job somewhere else. And the rent isn’t expensive at all, it’s £250 a week.
The exterior of the house is very nice. The building is 20 years old and it’s built from bricks. There’s also a big garden back of the house. And the best thing about this property is that there’s a swimming pool. And a garage for your car is in the offer too.
Interior of the house is old-fashioned but beautiful. It has got two floors. On the ground floor there’s a dining room, a living room, a bathroom and a bedroom. On the first floor are two bedrooms, a bathroom and a family room. The house is fully furnished so you don’t have to buy extra furniture.
If you want to get more information give me a call and I’ll give you the landlord's number so you can ask everything directly from him. Get in touch with me soon.
Yours,
Peter.
Hopefully it's the right place to post my writing. I'd be very appreciated if anyone could correct my mistakes.
Thank you very much!
