Looking for a nice house to rent (Mulhouse)

Hi. We will be moving to the Mulhouse region this summer from Grenoble. We are looking to rent a nice 5 bedroom house with a large yard. A pool would be welcome but not necessary. The house cannot be too far from a train or tram station for Basel. Two of our children will be going Don Bosco in Landser, so house must be on school bus route. We have already looked on websites like Le Bon Coin, Immo Region, etc. and are also working with a relocation company. We have not had much luck finding a suitable house. If have any housing leads, please let me know. Thank you and I look forward to meeting some of you at an InterNations event in the near future.
