The location was great, reasonably close to everything. I thoroughly enjoyed my stay and for the price its an absolute bargain. of course at such a low price there were a few small issues, notably the two "bedrooms" are separated by a curtain and some tactically placed shelves. meaning you can hear everything from the next room. And it was hard to utilise the kitchen when there was no salt, pepper, oil and sugar. I dont expect a stocked fridge but without these non perishables its hard to make a meal.
But despite these minor annoyances, The flat is PERFECT for a cheap stay in Barcelona, as I said earlier the low price renders all the small problems (and they are very small) meaningless.
