Elsa was a fabulous hostess - very accessible and communicative as well as flexible. The location was authentic - right in La Latina with lots of culture and restaurants. Elsa also provided a lot of great locations to visit and restaurants to try. If you want the true Madrid experience, I would highly recommend Elsa’s apartment. It was very clean and spacious. The only downside was the weather when we visited - it was very hot and unfortunately the fan didn’t reach the bedroom, but the rest of the apartment was cool!
