Our host Nicolás was very considerate - our flight was delayed and we got a little lost on the way to the apartment but he waited for us and showed us around the place. The apartment was simple but nice, and all the amenities that we needed were available. The apartment is about a 2 minute walk from Poble Sec metro station, which was very convenient for us, and there are lots of supermarkets and grocers nearby which was also really handy.
