Por the past years , we have been living in a basement, with a lot of hungus, darkness and humidity. That didn't help with neither mine nor my cat's asthma.
We worked really hard to buy a small flat that is finally on a floor!!! It is not something special and still needs a lot of work, as it is old, and needs renovation to be able to live in it. Kitchen, bathroom, floors, pipes, electrics all needs change!
No fancy stuff needed, just make it a home as soon as possible and some furniture to be able to live in!!
