Searching for a fixed postal address in Paris/France (remailing service, buero service)


Dear Sirs!

Several times a year I am staying in Paris.
So, in former times, my postal mail was send to "AmericanExpress client letter service" where I picked it up or it was resend for me.
But the service is still not available any more in Paris.
Then I searched for a service like a "remailing service" or a "buero service" to do so.
But I could not find anything valuable until today. Many companies found are closed already and only existing dead in the Internet.
Usually I do not need a "full service" like a usual buero service but I need a stable and usual postal address where letters can be send to and where I can pick it up or may be resend to my actual address/hotel etc.
I can find such services in many other countries, but not in Paris/France.

So, do you know any valuable service in Paris for that kind of service any more?
I checked some, found with GOOGLE, but often the location is not existing any more. Tel.-No. are wrong etc.
And I do not need a high priced buero service because I am not a business man, a journalist only, and do not need anything other than postal service.
Thank you very much for any kind of help!
