My wife and I, along with our 15 month old son, stayed at Gumaro's place for about a week and found it to be the perfect jumping off point to explore the city. Everything we needed was in walking distance. The place itself was clean, stylish, and comfortable. The beautiful balconies were a nice place to end our days.
Gumaro was a fantastic host. We had a small issue with the washing machine not working, and he got back to us right away and we were able to use the washing machine in his office next door without a problem. I would highly recommend staying here when visiting Mexico City.
