I had a very pleasant stay over my 4 weeks in the apartment. Arcelia is incredibly responsive and the the building doormen are very nice and helpful. It was really great to be so close to the Constituyentes metro station, where I could easily go to Polanco and other places, and it was nice to be in an economically diverse and non-touristy neighborhood after only staying in Centro and Condesa on past trips. Yes, as some commenters and have noted, there is street noise and music from neighborhood parties on the weekends, but I adjusted to the road noise pretty quickly and the apartment is in walking distance to great restaurants, laundry facilities, and stores.
