Elia (Karla's mother) was very welcoming and helpful! She welcomed us when we arrived and provided helpful tips to explore the city during our short trip. She met us the day we were departing and gave us two books of Mexican fables which was really thoughtful :) Karla's apartment is in a really great location but it can be quite loud on the weekend nights due to the venues in the ground floor. We had the apartment to ourselves during our stay so it was very comfortable.
