The company is located on the 11th floor, 3 of the 6 elevators on the ground floor can go to this floor, the other 3 do not go further than the 9th. Even though I did not pay for a repair/additions to my laptop (unfortunately out of my personal budget), the staff was very welcoming and attentive and took the time to explain everything. I'm sure their work is just as diligent.

Serious and attentive company. Resolution, Repair and fast follow-up. Very satisfied with the work done on my laptop. I recommend it.

Good morning, Cyril Bagiau, at Xefi, in addition to being a nice guy, is a seasoned professional, competent on all computer subjects where personally I am drowning and therefore sinking;) It is a pleasure and a need to be accompanied on these essential topics today.
