You get your time back
Listings, prices, messages at all hours, cleaning turnovers, Sunday emergencies: all of it leaves your week. What's left for you to do is read a statement.

The company
Before it was a company, Cosy'Part was the same idea in two heads, with neither of them knowing it.

Younes and Lounès met with the same leaning: property, and the conviction that a badly run home is wasted work for everyone. Separately, without ever mentioning it, each was circling the same plan — build something that would genuinely take the whole subject off owners' hands, not on paper. The day they realised it, the question was no longer whether to do it, but with whom. The answer was sitting opposite.
They started in Annemasse, minutes from the Swiss border, by signing the leases in their own names. Paying the owner rent every month, whether the property was full or empty. Fronting the furnishing costs, banking the peak seasons and absorbing the quiet ones. That is where you learn what a badly organised turnover actually costs, what continuously adjusted pricing actually returns, and how much local regulation can change the equation from one property to the next.
One rule survives from that period, and it still holds: we look after an owner's property as if it were our own. Upkeep first — a home degrades quietly, and nobody warns you. Income second: we chase it with the same obsession as if the money landed in our account. That isn't a sales posture, it is simply how we learned to work where it is our own money on the line.
The rest follows. An owner who sees their property treated that way hands us a second, then a third. Some introduce us to other owners they know. It is the only growth we believe in: slow, built on trust, without ever having had to convince the same person twice.
It is also why we turn properties down. If a property is badly located, poorly insulated, or sits in a council that has tightened its rules to the point of making the operation impossible, we say so rather than getting a signature. It's less profitable in month one. It's the only way to last.
Hover a value — or tap it
A property that doesn't stack up, we don't take. An owner who'd earn more managing alone, we tell them. Losing a deal costs less than running a property that doesn't work.
Cosy'Part is run by its two founders. You speak directly to whoever decides, not to a customer service desk.

Your property, our responsibility.
Why us
The real question isn't who we are, it's what you get out of it. Here are the four answers we give an owner before they sign.
Listings, prices, messages at all hours, cleaning turnovers, Sunday emergencies: all of it leaves your week. What's left for you to do is read a statement.
One fee, agreed up front, with no hidden margin on cleaning or on tradespeople. You get the original invoice, and the arithmetic is redone line by line the moment you ask.
What breaks gets fixed now, not at the next visit. A property inspected at every turnover doesn't age like one that gets opened once a year.
The platform accounts stay in your name, you block whichever dates you want, and if you leave, you leave with the listing, the photographs and the history.
What makes us different
Most management companies carry no risk at all: they collect a percentage, and an empty property costs them nothing. Cosy'Part signs the leases in its own name and puts its own money on the line. When we get a price or a season wrong, we pay for it ourselves.
That's why we turn properties down. If a flat is badly located, poorly insulated or sits in a council area that's too restrictive, we'll tell you rather than get you to sign.
Nothing we sell was dreamt up in a meeting. We run it first on the properties we operate ourselves, at our own cost.
No property gets lost in a portfolio: each one has a named contact who knows its history, its guests and its weak points. The team grows at the pace of the properties entrusted to us, never the other way round.
Annemasse, Geneva, the Lake Geneva basin: a year-round clientele of work assignments and relocations that most national operators don't know how to serve. What you learn there — reading local demand, adjusting a price, keeping up with rules that keep changing — transfers to any French town, and that is exactly what we do for the properties we take on elsewhere.
The written commitment
Some owners hand us a second property, then a third. It is the only satisfaction metric we really believe in.
Where we set the bar
Light, warm materials, nothing superfluous. A place that gets booked is decided before the first listing goes up.
Our properties
Three properties under management in Annemasse, minutes from the Swiss border. We'd rather show what we actually do than a portfolio borrowed from a stock library.
