If you are travelling on your own and spaciousness is not your top priority, the mini-apartment could be a considerable option. It's so close to the city centre and sightseeing in a safe neighbourhood, at an affordable rate.
My reservation for Mini-apartment was for 12 days, and I extended my stay for one more day. I was looking for a place near the CDMX attractions from which I could walk sightseeing, in a safe neighbourhood at night! It was exactly what I was looking for. Please consider the mini-apartment is too small and may not be appropriate for two travellers, though it can cover all the needs of a single traveller on a short stay.
Miguel was responsive, professional, and well-mannered, and I felt at home during my stay.
