We were supposed to be doing a house swap in Barcelona in the first week of August but it has fallen through - but our flights are booked 
So I'm looking for an apartment fairly last minute! Me, DH, 5yo and nearly 3yo. Where should we stay? Any tips? The house we were meant to be borrowing is in Park Guell, should we still look round there or in the city centre?
Any advice gratefully received!
