I want to start by saying Alejandro is an incredibly host. He helped us work through the every issue that we came across and was amazing to work with.
That said, our stay had some unfortunate bumps. The loft apartment is old, the bedframe was unstable, and the water heater took a long time to heat up water. Be aware that Mexico city can get very cold at night, which makes the loft frigid during most of the day if the two balcony doors aren't left open. It's noisy outside, but no problem with earplugs.
The balconies face inwards, which means they don't get sun during the day.
