Location: very close to old city centre, 10 minutes walk to Malaqueta beach via tunel short cut, 10 minutes walk to El Corte Inglés, 15 minutes walk to train station Centro Alameda. Basically, all is within the walking distance.
Apartment: Big enough for 2 people, with all the necessities for your stay. Washing machine, iron and Netflix are nice bonus!
Over the weekend, neighbors from opposite block of flats like to play loud local music, but if you are planing to stay late in town, then it is not a problem.
Overall, enjoyable stay :-)
