I would 100% recommend Elena's apartment. It's not only beautiful but has plenty of space for a big family. Elena is very friendly and goes beyond her host duties to make you feel like you own her apartment for the time rented. She tells you about places to go, where to eat. The apartment is centrally located, you can walk to Plaza Mayor, Mercado La Latina, Mercado San Miguel and enjoy different restaurants and cafes in the neighborhood. We truly enjoyed our stay in Elena's apartment.
