YES, this apartment was designed by Luis Barragán! There aren't many opportunities to stay IN one of his works so here's your chance. The apartment is really great, very clean, has everything you need and, did I mention, designed by Barragán. Evelyn is very responsive and a helpful host.
The only downside is its location which is very close to a highway and not in an interesting neighborhood. The highway is pretty loud so bring earplugs if you're a light sleeper.
