Alex and May's apartment is incredibly spacious and perfect for our friend group trip. The rooftop is fantastic, and the view of the city cannot be beat. There are so many great communal spaces, which made it very easy for our group to have places to socialize without feeling overcrowded. Everyone on our trip seemed to sleep well in their beds, and it is a great value for the amount of space you get. I would highly recommend this apartment if you are looking for a large place with lots of common spaces.
That being said, I feel obliged to mention a couple of things about our stay which may be useful for future guests.
On our third night, the hot water boiler broke so we were without hot water for a couple of nights. May was responsive in sending the plumber over a couple of times to get the boiler fixed, so we had hot water restored after a couple of days. They said it has never happened before, so hopefully it was an anomalous experience.
On our fifth night, the elevator in the building broke down and we had gotten stuck one day until a friend was able to open the door for us. We had abided by the elevator's carrying capacity, but perhaps it is finickier than its stated capacity. After a few days out of commission, it was eventually repaired 4 days later so we no longer had to take the stairs up to the top floor. I would recommend not fitting more than 4 people in the elevator at a given time to avoid any possible issues.
As a prior guest had mentioned, there is also only one set of keys which can make entering/exiting the unit tricky. We luckily were able to coordinate when people could come/go, but having another set of keys would make the stay a lot easier. If you are a family traveling together, it may not be as big of an issue, but for friends/couples who may be coming and going at different times, be aware that you may need to coordinate tightly about entries/exits.
Finally, it took a few days to get a cleaning halfway through our stay, and it would have been great to have a little more responsiveness in getting that done. In the end, we were still able to have our apartment cleaned for our longer stay, though it was only 2 nights before our departure. I would plan out a day in advance for cleaning since it may take a while to get a cleaning scheduled.
Overall, I would stay again at Alex and May's apartment if I'm traveling again with a big group. It is a fantastic deal for the amount of space it is, and the location next to two bus stations is great for getting around CDMX. May is also responsive, which I appreciated since the housekeeper normally the point of contact was out on vacation for the entire duration of our stay. It is a great space at its price point.
