Maribel's place is as central as you can get. It's walking distance to everything and is surrounded by beautiful little boutique stores and eateries. She is so lovely, and even washed my clothes for me with hers! It was so kind of her :)
Her living space was nice, but very cold in winter as she leaves windows/ doors open. She does smoke inside the kitchen (but uses a variety of air purifying/ freshening techniques to rid the smell, so you can't actually tell most of the time).
I had a lovely stay nonetheless.
