We had a wonderful week long stay in Laura and Lucia's apartment. Laura met us at Colon metro station and it was a quick one minute walk to the apartment (and a very quick metro journey from the airport). The apartment had everything we needed (wand very secure with a 24 hour door person) and thanks to Laura for the welcome goodies.
The apartment's location is fantastic and within easy walking distance of the Russafa and the Old Town. We also visited the beach, BioParc and Aquarium. I am veggie and can recommend Copenhagen restaurant in Russafa, we visited twice! (though do book as it gets busy). I have no hesitations in recommending staying in Laura and Lucia's place!
