I stayed at this studio for 35 days. It was a perfect experience. I had to work from that studio so I asked Carlos if he had an extra monitor. He said yes but the monitor didn't work with my laptop. Within a few hours, he ordered a new one from Amazon which worked perfectly fine.
The wi-fi speed was great, pretty much the same as what I have in Canada. The place is clean and efficient, equipped with anything you might need for your stay (short or long). Carlos is also very communicative and you can ask him any kind of question you have.
The location is close to many cafes and restaurants, all within walking distance. Uber to Roma and Condesa would cost you less than $5.
