We were met by Cai, Lucy's boyfriend upon arrival and he was very helpful to show us around the flat and tell us a few tips on the building and neighbourhood. Cai also sent us a list of recommended places to eat and drink around Poble Sec. The flat was just as listed and very comfortable. The weather was very hot so we slept with the windows open. It's an active neighbourhood so if you're a light sleeper I'd recommend ear plugs. There were fans to help cool things down at night.
We really enjoyed staying in Poble Sec as there were many bakeries, cafes, and restaurants. Every morning we had fresh croissants, espresso, and picked up fresh fruit at the grocery store. We walked to all the main areas from the flat or if we didn't feel like walking it was easy to catch the subway around the city. Highly recommended, can't wait to go back!
