Mauricio's flat is nicely designed, pleasent and generally clean. I felt well there. It's not the best location in Geneva (but it seems to be safe), but it's in a walkable distance to both the old city and the UN and other places.

I haven't met Mauricio personally. He seems to be an easy going person and my only small peeve, if any, is that he may be a tad too relaxed, particularly when it comes to communication.
As a rule, it took him a few days to answer any message from me. Still, my stay in Mauricio's place went smoothly and I can recommend his apartment.
