Me and my girlfriend stayed in Helen's and Andrew's place for 2 nights for our stay in Barceona. They themselves were on vacation but Anastasia, a friend of theirs stayed in the room downstairs and was very friendly and helpful. Communication was easy and instant. The bedroom was very nice and the view and balcony magificient. The A/C kept us cool on the hot summer days and they provided us with filtered, cool water when we arrived. Coffee, beer and some snacks were also in the fridge which came in handy. The city center is not quite around the corner, but the metro is close by and takes you there in a few minutes. All in all a great place and hosts, so we can definitely recommend staying there.
