As far as location goes, Rico's apartment here is really cool if you like the laid back atmosphere of Bernal. Located just "behind the hill", it's walking distance to a number of coffee shops, restaurants, bars, stores, etc. If you want to go to an event or properly go out in the city, you'll be driving though, so get a rental or plan to Uber a lot. There is ample street parking if you're willing to walk a few blocks.
Rico is a very attentive host. We didn't meet IRL, but we messaged quite a fair bit. Almost every day, he'd message me asking if I needed something. This level of attention is definitely appreciated but certainly not necessary in my opinion.
The apartment is cool on the inside, it's a basement apartment, but I'd say it's surprisingly well lit. There were tons of little fix-ins all around the house, you could tell there's a lot of attention to detail (ie: cookies/snacks on the counters, a few beers in the fridge, an ample number of towels, etc).
The only negatives things were that there is no kitchen/microwave and the bathroom is small. If you're planning on eating out basically all the time, not having a kitchen is pretty fine but you know, YMMV. The bathroom is small and the shower is such a tight squeeze that the space saving design of the shower is both entertaining and effective.
