I would absolutely stay here again. Monica was a great host- very responsive and prompt and available to answer questions about the city and gave us great recommendation for places to eat and see. She and her brother were super helpful.
The accommodations are modest but included everything we needed (3 adult men). The spiral staircase seemed weird at first, but was a fun part of the overall charm. The building was quiet and well situated within easy walking distance to everything we wanted to see! Next time I'm in Mexico City, I'll be staying here!!!
