Mireya's place is great. It's located in a good neighborhood - metro is super close, there are places to by ready food and there are shops to buy ingredients to cook yourself. The neighborhood is quite quiet and the best part - it's quite close to the city center - if 30-40 min of walking is not frightening then you almost wont need the metro for exploring the historical center on the city.
The apartment is tidy and there is everything a traveler would need for a weeks stay. Mireya has travel guides and maps to help you get around the city.
Only one thing to take note of: The flat is on the first floor and walls are a bit thin, so if you are a light sleeper then the noise from the street could be a bit of a problem, but as stated before it's a quiet neighborhood so it's not a huge issue.
We had a great stay.
