Staying at Pam's and Pepe's place was wonderful. Pam and Pepe are the kind of people who love to engage with you but also respect your space if you are looking for more of a private stay. I stayed for 5 weeks, 4 of which I was heavily working and they were well accommodating to my privacy while I was working but also very open and engaging when I did manage to find time to talk with them. I honestly regret not talking with them more because they are such interesting and vibeful people. They also both speak really good English but are open to practicing Spanish with you.
The place is well kept and comfortable. Location is fantastic and after being there for over a month and exploring around, I can't imagine a better location. Pam and Pepe are full of suggestions of things to do and can offer great insight on how to make good use of your time in Mexico.
Overall the experience was great and I had no issues whatsoever with my long stay. If I do return Mexico City I will be looking to stay here again.
