Estación Federal is a nice development with these lofts, a coworking space, a nice cocktail and beer bar, coffee shop, pizza place, and taco truck (which wasn’t open). Very convenient to the PedWest border crossing, but you’ll want to Über anywhere else.
Note that the listing had photos of and mentioned a different loft number, but the photos were mostly representative and the difference wasn’t an issue. In fact, the couch was better for sleeping than the one pictured.
Do bring an eye mask and earplugs. This is pretty standard for TJ though. It’s just not a quiet city.
The person who checked me in allowed us to store our bags until the room was ready. He was very friendly and helpful.
