Great apartment in a fantastic location. I stayed in Yolanda's place for a month and I really loved it. The apartment is clean, cozy, in good condition, and with a real homey feeling. Only down side is that the kitchen is small, but it's fine for basic cooking and food preparations. The location is just perfect - short walk from Plaza Mayor and right by La Latina metro station.
By the end on my stay it really felt like a home away from home. Highly recommended!
