Laura was exceptionally prompt with her responses and told us all we needed to know. The apt is comfortable, well laid out, and clean.
It's located in a great, clean, and secure building that's a mere 5 minute walk away from Zocalo, but well away from the night time noise of the square. Just the restaurants, museums, sights, sounds, cathedrals, ruins, etc... within a 1-2 km radius are enough to keep you busy for several days.
Views from the roof top terrace are fantastic, night or day and it's a comfortable spot to hang out and unwind.
Without any hesitation I'd readily recommend this to friends and family looking for an apt in CDMX.
