This apartment is very beautiful, and felt like I was traveling back in time. The attention to detail with the wood-carved furniture was stunning. I took advantage of the amazing selection of books!
As mentioned in previous reviews, yes, it comes with some quirks because it is a very old building- like occasional odd smells and a very small kitchen/bathroom - but if you are low maintenance and want to feel like you live in the old Mexico City, you will come to love it. I didn't have any problems with the noise outside, but I live in downtown Chicago so maybe I'm used to city noises. Also the shower water pressure was great - the sink has lower water pressure, but I used the filtered water provided for brushing my teeth, etc.
As a girl traveling solo, I felt perfectly safe here - would just have preferred to have a mirror in the bathroom for vanity sake :) It was very easy to pick up Ubers from XEW across the street and it is very walkable at all hours to get anywhere.
