Great and quite big flat if you are staying as a couple. Big bedroom and living room and nice kitchen with loads of devices to make a perfect breakfast including fresh juices, smoothies, toasts, etc.
Location is nice in case you are ok with walking - 5-7 min from metro, 30 min from Playa Cabanyal/Port, 10 min from El Corte Ingles, 15 min from Cit of Science.
Very approachable host, replying in 5 min on any kind of request. and living just next door.
