The flat was as described and nice and roomy for two. The finish was a little dated but we were happy because it was quiet at night we were able to sleep well. Close to public transport and the hop on hop off bus has a stop not too far away so that was useful too. Recommend this as a good way to see all the main city sites without any hassle - take two days over it.
Don't expect any extras like soap. No welcome pack eg bottle of water or any cooking oil, condiments etc. Mini supermarket nearby which stayed open late so that was useful. Arrived at 10pm and had to pay 25 euro late check in fee (which surprised me as Barcelona stays open well into the night!).
