Excellent communication and quick to address any questions, issues.
Personally, I was very grateful for Alfonso letting me check in like 2am as my flight was super late. He personally greeted me in that late. I found the location to be safe, within 15min walking distance to parque México, spacious and clean studio. Doesn't have a fridge or stove as mentioned in the listing, I didn't need them. So it was a great value for me.
