My Flat in Caranza, Ferrol

I live with my brother in a flat located in Caranza, a district of Ferrol in the north of Galicia. Our flat is in a residential area on the seventh floor.

It is small, featuring a living room, a kitchen, a bathroom, and a bedroom. While I do not have a lot of furniture, I have everything I need.

There is no balcony, but I can see a small park from both the living room and the bedroom. I enjoy living here because it is near my NCO School and it is cheap; I pay 200 per month. However, the flat is quite noisy due to heavy traffic.
