I stayed for 6 weeks and it was great. While the area has a few great little places, it's fairly low-key. Which was great for me since it was fairly quite and I had a lot of work to do. however, while the more trendy neighborhoods of Roma and condesa aren't horribly far, they aren't as close as I would like.
I would recommended the place for long term stays or people wanting a more quiet Mexico City experience.
