I'm a 43 year old, English guy from London. I've been in Barcelona for 5 years and I work for an apartment rentals company in the city. I've previously (and all my life) worked in restaurants, bars and private members clubs (London).
I would say that I'm friendly, relaxed and accommodating, unintrusive and respectful, so you'll be sure to have a comfortable stay here in this great district of the city.
I know where most places of interest in the city lie, so can provide you with travel and tourist information, guaranteeing your visit will be easy and organised.
