The overall process was quite smooth. The car (DS-3, 35000 miles) was in good shape; no major damages, except for some scratches on all wheel rims are to be expected after normal use.
Soon the tire pressure indicators prompted to check the tires - which all were visually OK; and some air needed to be added to reach the recommended pressure.
We did not require any service or help during the rental period. At the end of the rental the return experience was very positive, quick and professional.
