The location of this apartment is hard to beat. Right in the middle of Centro histórico. 5-10 minutes walk to the Zócalo, and literally next to the metrobus that goes from the airport or the TAPO bus station. The subway is also really close.
When we arrived, there was no one at the gate of the building. Had to call Juan and his neighbor let us inside the apartment. I did not have any Internet access on my phone, so that probably did not help to get in touch with him.
The apartment was very clean and nice with a kitchen, fridge, television, coffee and tea.
It was more than enough for 2 people with two rooms.
Was a little bit hard to get hot water for a whole shower but it was feasible.
Juan sent us a lot of information about his city during our stay.
The only drawback was a cat inside the courtyard of the building that was meowing practically every 10 minutes all night long during our whole stay. I'm surprised the other neighbors from the building did not complain about it.
Apart from that, it was overall a good option in Centro histórico of Mexico City.
