Handy!
A handy is the word German speakers often use to describe a mobile phone. In this case we're describing a mobile home; not quite the same as they're kind of tricky to put to your ear. However it is a handy place; perfect for someone looking for an unassuming, but comfortable, holiday retreat and it's set in a great place, just a short walk from civilisation (in this case a bar restaurant)
The mobile home is set up with three bedrooms (your friends will be pleased) and one bathroom. It's connected to mains electricity and even has air conditioning. Mobile homes, like mobile phones, have come a long way.
