Camila's apartment is in an exceptionally convenient location for exploring the sites and attractions of San Telmo. The downside to its location is that it is immediately next to a major highway, which means it has a lot of traffic noise. I had read this in previous reviews, but want to reiterate that it is quite loud.
Florencia communicated with us for our stay and was gracious in allowing us to arrange a late checkout to accommodate our travel plans.
My Spanish isn't great, so I think I missed her instructions about how to use the hot water heater, which meant that we didn't have hot water during our brief stay.
