I really liked the hotel: right by the zocalo, nice shower, comfortable bed. Spotless room with a window and balcony. Breakfast and available coffee were nice to have. Digital guide is innovative and very convenient.
I would stay there again without a doubt if needing accomodation in the center, I was happy with my stay.
Be aware though : you will not find anything to eat past 8.30/9h in the immediate vicinity as the neighbourhood is then dead. Most of all, there are constant events or protests in the historic center and many roads - even the zocalo - are blocked for cars and pedestrians during the day, making it hard to circulate (and forget the uber).
