The apartment was in a really great location for me - walking distance to the downtown core, and very close to grocery stores (Mercadona right across the street), traditional Mercado a couple blocks away, great coffee shop right at the corner, and just up the street towards the Mercado there's a great little restaurant which serves traditional Andalusian food in menu del día format for great (cheap) price :). Corte Ingles and Starbucks are only about 5 minutes or so away. Walked home from downtown core a number of times at midnight along C/Martinez Maldonado and never had a problem (seemed to always be a fair number of people on the street, and felt safe). The hosts were very friendly and extremely helpful.

The apartment is on the second floor, so there is some noise from the street at night if you are a light sleeper (but I didn't have a problem with that).
