My place is close to but NOT in "El Centro", It is just above "El Mirador" on Salida de Queretaro, Located just 15 -20 min, walking to the Jardin, easy public transportation, 10 min. bus ride for 7 pesos (¢35), taxi or Uber for under $3. You`ll want to taxi home, as it`s a steep walk home.
Quant Mexican neighborhood, Valle de Maiz. It's good for couples, friends, and families (with kids), and most pets are welcome, but please ask first.
