BF and I stayed here after a friends wedding in Queretaro, and it was much needed rest and relaxation after non-stop traveling. Love how close everything you would want/need is, food, drinks, pharmacy, anything.
We felt safe to walk at night and not much noise going on during our sleep except for after 9 - 10am but we are out and about by then. Ana Paula's instructions were easy to follow on how to get in/leave apt. Bed deserves 10 out of 10 stars, and we did use the fan a bit, but it's very strong in case you do get hot.
Roma Norte is a great place to stay in Mexico City imo.
