I (beneficiary) first scheduled to have my medical done in Lisbon but they could only set me up for the October 20th and the scheduled interview was set (at that time) for September 28th. Since it was a big discrepancy, they did say for me to try schedule it for Paris because chances would be, that it could be scheduled earlier.
I did managed to even chose a date that fit perfectly which was closer to the date of the interview, so I thought we would be staying in Paris for a full week to deal with everything (keep in mind that for the French appointment, you will also need to go do the exams before the medical appointment at the set places they have).
So I had my medical appointment scheduled for September 24th and did the blood/urine exams and the x-ray on the 22nd. They where in 2 different places. The results were done on the same day. The results for the blood/urine were sent directly to the doctor, while the xray, we had to pick it put later that day.
The only thing I have to add is that french language is the preferred language but some places had someone that had portuguese people or someone that spoke portuguese and helped. They do try to talk english but they aren't very comfortable in their abilities to speak it, that's why they stick a lot with french. In no way they were ever rude, they just really feel like they don't speak it well.
