During the booking phase, and once the booking had been confirmed communication with Ernesto was easy. I booked well in advance of my stay and when the time came Ernesto was very helpful. My flight into MEX arrived late at night, and once I had retrieved my baggage, travelled by Taxi and arrived at Ernesto's apartment it was close to 0100. But Ernesto was there to greet me and welcome me to the apartment and show me around. I was pretty tired so he offered to give me any assistance I may need or answer any questions the next day.
A friend in Mexico City suggested I find an apartment in this area, as it is considered a safe part of the city. I was comfortable walking around the neighbourhood both day and night. With convenience shops a block away, coffee shops nearby, local eateries serving typical food that was both inexpensive and very tasty all within an easy ten or 15 minute stroll, the apartment is very well located for anyone wanting to explore on foot, bicycle, or car. I walked to Chapultapec to see the Castillo and museums, as they are close by.
The apartment is exactly as pictured. Although there is a small kitchen, I chose to eat out as the food is so good, and there were so many options to choose from.
Ernesto periodically asked how I was making out, and offered suggestions on places I might be interested in seeing. He was very helpful.
I will return to Mexico City in the future, and I will hope to stay at Ernesto's apartment when I do.
