Erika's apartment is located close by Abasto shopping center and several subway stations, you can easily use Uber as well.
She is a fantastic host, she greeted me upon arrival with a warm cup of coffee and she made sure I felt like I was at home, her apartment is pristine clean and it has a nice patio in case you want to chill out on the evenings, there was even a tasty alfajor waiting for me in the room!
For the price you pay this is a unique opportunity so if you're traveling on a budget like I did then you'll get the best value out of your money.
Erika, thanks so much for all the recommendations and overall kindness, Buenos Aires is a better place thanks to people like you.
