My stay in Barcelona was great thanks to Norbert. His place is Located centrally although you may want to take the buses / metro for some places if you don't like to walk a huge amount. Their are also rental bikes close by. He gave me a towel and offered me water and croissants. His bathroom is small and the room is a bit stuffy but thankfully he had a fan. Norbert's English is improving and he was able to communicate with me well.
