Writing an informal letter describing a house for rent

Dear Clara
How's everything? I hope you're well. The reason I'm writing is because I think I've found the ideal flat for you!.
It`s located in a really nice place called Miramar. It`s just a block from the beach. It`s a quiet area, and you can reach the forest in less than 15 minutes on foot. There's a large and beautiful camping site in there, also there`s a very well known restaurant, where you can eat a large variety of fish dishes. The rent for the flat is $2500 pesos(ARG) a week.
The flat is in a 10- storey building on the 7th floor. It`s outstanding outside. (this does not sound natural - do you mean it has a nice view? Or that the outside of the building looks nice?) It has a balcony where you can see the pedestrian street and the shops. There is are plenty of trees. Also you can go to the roof to dry up your clothes and in the afternoon there`s a magnificent view from up there.
Inside the flat is huge and comfortable. It`s got three well maintained bedrooms and a bathroom. It`s fully furnished, with built in wardrobes. Also there`s a fitted kitchen and a living room with a tv and a dvd player.
Let me know if you`re interested. I can easily talk to the owner for you.
I hope I`ll see you soon!
Best wishes
Daniela

Excellent writing Daniela! - I have made a few very minor style changes.
