Following booking with Elio/Wilken all my queries regarding arrival and check-in, as well as local transportation were answered promptly. Their colleague Leticia was extremely polite and helpful up on arrival also, providing me and my friend with useful tips regarding the metro and getting around Barcelona. The apartment itself was also lovely and overall I had a fantastic stay. Would certainly love to visit the city again and if/when I do I would be very happy to stay in this same appartment.
