Maribel is a life-saver: I arrived in Mexico City just before midnight and without a reservation. I took a shot by reaching out to a few hosts, including Maribel, before heading to a hotel. Maribel responded within ONE minute! She was more than willing to host me and my pug without any hassles whatsoever. From the get-go, she was helpful and thoroughly accommodating. She even directed me to a nearby veterinarian the day after our check-in.
The place is super clean. Every day her cleaning crew disinfected the common areas. That's attention to detail that you just do not see everywhere! The room itself is very comfortable and had all the amenities (and more!) that I could want during a four-night stay. It has its own private full bathroom. And perhaps more impressive is that it has a kitchenette with a mini fridge. That kitchenette came in very helpful since I had to cook food for my pug.
Roma Sur is a beautiful and very eclectic neighborhood. It is safe. Maribel's home is between two subway stations (Centro Medico ~10 minutes away to the east and Chilpancingo ~7 minutes to the west). There is so much to do (read: eat!) nearby. For example, the Medellin traditional marketplace is a few blocks away.
I am definitely saving Maribel's place for when Rocky and I return to CDMX in six months.
