Uliv's apartment and the entire neighborhood felt extremely safe. We walked around at night when it was pretty empty and the neighborhood felt homely. The security downstairs was thorough and even stored our bags after we checked out. Uliv provided a pack n play for my toddler and was very responsive when we needed an extra fan. It was delivered within 5 minutes. If you go during the summer, you may want to book a place with a/c, but we went in November when opening the windows was just fine to let in a nice, cool breeze. Closing the windows at night also eliminated most of the sounds outside, but Mexico City is a busy city so you can just put on some white noise and we slept very peacefully. I am a very sensitive sleeper, so this was very important and the beds were so comfortable. Some of the reviews complained about the showers, but there are clear directions posted on the shower tile and we never had any issues at all. Overall, we enjoyed our stay and it is well worth the price!
