My wife and I had a good time at Mercedes' loft! The place came with all the necessary furnishings, with a bed that was quite comfortable compared to other rentals I've stayed in. The neighborhood is quiet but close to all the action, a subway entrance, and a few restaurants. My wife and I enjoyed the local feel, as most other places we stayed in during our stay in Buenos Aires tried a little too hard to pump that old, European (bourgeois) feel.
We did have an issue with the heating system smelling a little strong, as well as being irregular. The hot water was supposed to last up to 15 minutes but no matter what we did, it would only ever last 2 minutes or less. We had a little trouble reaching Mercedes for help when we couldn't get it to work, which was an issue as it got quite cold inside. Other than that complaint, we were very satisfied with our stay and would recommend to anyone looking to have a different experience in BA instead of the typical, cookie cutter experience hotels in the city would offer.
