Our stay in Rafael's apartment went really well. We stayed at his apartment for 2 weeks longer than we originally planned, for a total of 6 weeks.
Rafael is very sweet, and is a very considerate and active host. The day we were leaving, my girlfriend got sick, and Rafael knew exactly what to do. He ran out and got us some medicine to help her feel much better. He made what could have been a terrible travel day into a much better one :)
If you need anything, he's there for you. We had a few issues while we were staying in his place and he took care of them right away.
The space itself is nice. The wifi is relatively fast and stable (by Mexico City standards). Good enough to do a live stream / work if you need it.
The kitchen is well equipped, though it is small, so only 1 person at a time in the kitchen.
We liked the big TV and lounge space. Both beds are comfortable (2nd room's bed is firmer than the master bedroom's).
We didn't expect for the apartment to be so full of furniture, but it wasn't much of an issue.
The main downside for us was abnormally the high heat in Mexico City at the time, and that we had to keep the windows open to keep cool. At this time, the apartment didn't have any screens on the windows, so there were lots of bugs & mosquitos and we got bites. We also had to deal with the neighbor's cigarettes and the smoke from wildfires near the city. Unfortunately, the two fans provided were extremely loud so we tried not to use as much as possible. I don't think these issues would be much of an issue if it's not the hot season.
The apartment is about a 5 minute walk to the metro, and about 10 minutes walk to a metro bus. There's lots of busses that run in front of the building (all headed south).
It's a 7 & 11 minute walk from 2 larger grocery stores. There's also a street market on Tuesday with fresh veggies and good tacos.
The neighborhood behind Rafael's apartment (going east) is very nice and there's plenty of little places to pop into.
Rafael's place definitely has a permanent place on my Mexico City list.
