As a solo young female traveler, I would recommend staying here! As a great surprise, my new AC unit was working too as a great added bonus! I would recommend for anyone. It felt safe and very clean and I much preferred it to staying in one of the hotels on Reforma.
Pros: 24/7 security in the building, filtered water in the kitchen, washing machine and dryer, cute residential neighborhood, air conditioning, tons of space, everything felt very new, felt safe walking around at any time of day.
Con (and this was very small, wouldn’t prevent me from staying here): the walls are a bit thin so the noise from your neighbors in the building can be a bit loud if you have noisy neighbors (I found the noise from the street to be fine and minor!) They do everything they can by providing a white noise machine and earplugs.
Overall; would stay here again in a heartbeat!
