I loved my time at The Brit so much that I actually booked another stay here when I was checking out (I stayed here at the beginning of June and the beginning of July). This is a fairly new establishment, I was told that they opened in December of 2021. The location is great, it's about a 20 minute walk to most things in Roma Norte and Condesa and then less to see what you want to see in Juarez. This was my first time visiting Mexico City and staying here was very convenient. ALSO, having an in-unit washer and dryer was also very convenient since I was traveling for a whole month.
I also liked how there was plenty of office co-working space on the rooftop (both indoor and outdoor). The gym was small but a nice addition--I only went once to use the treadmill. I stayed at both 106 and 406, I really liked that the unit was on the corner of the building so you could see both streets outside the floor to ceiling glass walls. That being said there is a trade off to the walls being made completely out of glass--you can hear everything so I highly recommend packing earplugs and an eye mask to help you sleep better.
Also, I think the pictures make the units look smaller than they are. They were actually quite spacious and the bed is huge.
