Al and Uri are lovely hosts. The apartment has everything you need for a great stay. El Raval is not for everyone- it is not the cleanest or the prettiest district in Barcelona - it has people from all walks of life, some of whom are a little unsavoury but most are beautiful - if you're a seasoned traveler you'll find it interesting and it's within an easy walk of the port, Eixample, Las Ramblas and El Gotico.
