When we arrived, the electricity was out and we had to have an electrician come and install a new fuse in the breaker. This is fairly normal, I guess, when it rains heavily in San Telmo. Geraldine was amazing in helping us coordinate a quick fix, and then everything was perfect from there. She was also readily accessible and super helpful in coordinating transportation to and from the airport, providing recommendations for dinner and other meals, and checked in on us to make sure everything was OK with the rest of our stay.
The location is nice and secluded, and everything was so cute... from the decorations inside, to the patio with plants, to the rooftop area with sun and bright colors. I would recommend staying with Geraldine to anyone, just try to get there when it's sunny outside and everyone's life will be easier :)
