Honestly,calling is easiest.
Fifteen minutes on the phone is enough to know whether we can do anything for your property. No switchboard, no endless form: you reach one of the two partners directly.
Our two lines
+33 6 95 67 19 41+33 6 09 78 42 69Numbers shown in international format: some of our calls come from Switzerland, and a French mobile number can't be dialled from abroad without it.
Where we operate
Our two operating areas are Annemasse and Lyon. We don't receive visitors there: we come to you to view the property, wherever in France we're working.

Where we operate
Based in Annemasse and Lyon.Available across France.
Our teams are physically present in the Annemasse area and in Lyon. For a property elsewhere in France, we'll review it and tell you honestly whether we're the right people — or whether you're better off with someone on the ground.
The cross-border market
Annemasse is a market of its own: more than 110,000 people commute to work on the Swiss side, and a furnished one-bedroom costs three times less in Annemasse than in Geneva. Demand for medium-term lets — assignments, transfers, relocations — is constant there, outside the tourist season and outside the night cap. We've been working that market from the start, and it is where our method was built: the same one we apply wherever we operate.
