It was a nice place, very close to my favorite street - Av.Tamaulipas.
Wi-fi is great.
But it's difficult to works because you have 3 types of noises: 1) loud street; 2) neighbors 3) crazy construction work. You can always work in cafeterias nearby, so it was not a huge problem.
Just make sure you don't vitally need: coffee machine, microwave & rubbish bins in the building, cause it doesn't have it :) I was pretty comfortable though, but make sure you are not traveling alone, for 2-3 people it's amazing, but for being alone as a girl, might not be so cozy. Anyways - overall my stay was good!
Cristian is SUPER host, was super responsive and accommodating - 5 out 5 for his hospitality :)
Thanks so much!
