The host was very helpful and was waiting for us at the apartment when given half an hour notice. We were told that we could ring for help at any time and there was lots of good information waiting for us in the apartment. The apartment itself is really lovely - a stylish and modern design whilst still being homely and spacious. The terrace is huge and because the neighbourhood is so quiet, you feel very settled, relaxed and immersed in Barcelona. The area is more quiet than the centre and is not really very touristy at all - this can be a blessing in disguise though because after sweating through the busy city all day it is very welcome to walk off the metro into a chilled out peaceful area (which does still have cafes, bars, 24h shop, supermarket etc.) There are good transport links - a 3-5 day metro pass is great value and really useful as you don't want to waste time walking to the other neighbourhoods / attractions you are interested in.
