This is a great apartment on a nice, quiet street in Roma. I'd stay at Luis' place again.
It is a hip apartment with lots of space and amenities; the location is great and walkable (especially to Condesa); and Luis was a great host and very responsive.
Unfortunately, we were in CDMX on an unusually hot weekend, which made it rather warm for us. And we couldn't keep the windows open because of the mosquitos. Luis brought us a fan that helped cool down the rooms at night, but it was still a bit warm. If you like it cool, I recommend asking for a fan (or two fans) to make sure you have a comfortable stay.
Otherwise, it is a great place to stay. I recommend this apartment!
