I stayed at Rodrigo's place for a month. Here's my pro and con list.
Pros:
1. The location is central. You can get to Mexico City's center by walking 25 minutes or taking a 5 minutes subway ride. You can also easily get to Juarez and Roma in a few bus stops.
2. Very "local" with few expats. Food around is generally inexpensive. On the weekends, there is a large street market.
3. Never had issues contacting Rodrigo.
4. The place has a washer which is more practical than a "lavadero".
5. Generally, the place have most things that you need.
6. The internet was speedy enough for face-to-face meetings and HD videos.
Cons:
1. Kitchen doesn't have space for food preparation.
2. The lights doesn't have fixtures so there are holes in the ceiling. I think this can be a cheap fix which will make the place much better.
3. The bathroom ceiling have some mold and could use a peel and repaint.
4. 1st floor unit which other tenants can see you when your curtains are open.
