Calm Scottish Fold cat accustomed to apartment living

This Scottish Fold cat named Milo has lived with us for almost three years. He's a very calm cat who prefers to observe rather than run around. Most of the time he stays near the window or sleeps on the sofa. He's very clean and has never caused any problems in the apartment. He simply enjoys being in the same room as people without necessarily demanding a lot of attention. Unfortunately, we have to travel more often for work and we don't want him to be alone for long periods. So we're looking for a stable family who can offer him regular companionship.
