Montserrat's place was wonderful! Centrally located to everything and within walking distance of most. Cheap and quick to go anywhere via the metro at Insurgentes or by Uber. The apartment was spacious (lots of room for me to do my morning stretches) and the kitchen stocked with coffee and tea, which was an unexpected, pleasant surprise. It was great to have the filtered water and a small space to store some modelos and light groceries. Many of the reviews mentioned noise from the street, however it seemed normal to me for a lively area of the city and I found that if I put the fan on at night it drowned out any noise from outside.
It was easy getting in and once the door guys knew who I was, it was simple to come and go anytime, even super late at night (you just ring the doorbell outside and they will let you in). Although I didn't get to meet Montserrat, she was quick to reply to questions via Airbnb message and I felt like I could reach out with any concerns and that she would reply promptly if needed. I felt safe in the neighborhood, even late at night. I definitely want to come back and would certainly stay here again :)
