The issue with the water also happened to us. I had to solve it myself by looking up how to turn it on on YouTube. I sent the host the link so hopefully she can send that to the next guests. It looked like she knows about the problems and just waits for them to pop up and solve them with the guest rather than fixing it properly.
2. This made me unable to sleep at night. I woke up every night screaming. You cannot lock the doors. You can just shut them. Even when you leave the house. So somebody could easily open them. There is a 24 hour guard, but the guard was not there 75 percent of the time when we passed. It did not make me feel safe at all. Quite the contrary. Anybody who has access to the building such as any neighbors or any airbnb guest can hack into any of the other doors. Very insecure feelings, and I woke up every night screaming. No kidding. Please put proper locks on the doors.
Other than hat the location is perfect. Two minutes away from the main food street and 5 minutes away from the reforma Avenue.
