If you are traveling alone to Sevilla, I would not recommend staying here. This place is quite a walk to the metro, and not close AT ALL to city center. The neighborhood is a bit sketchy, and the bulding is gross. The front door is shattered and you have to press a collection of wire and metal to open it from the inside. The apartment itself smelled so badly of smoke that I had trouble breathing and sleeping.
However, Maria is very kind and flexible with your schedule. I appreciated how she was not phased by my schedule changes.
