We 100% recommend a stay at Luis's apartment - everything was perfect - the communication, the welcome, the location, the apartment - centrally located but quiet, very comfortable bed, little touches that were really welcomed (coffee, water, biscuits) and you can tell Luis has thought out what guests need (umbrellas, even a little iron and ironing board). We enjoyed chatting with him even in our terrible Spanish. Both Luis and the apartment are gems! Will definitely book again when we are next in Barcelona.
