Our hosts were very helpful when we arrived, they kept in touch by phone and came to let us into the penthouse. It was exactly as decscribed and 4 of us enjoyed our stay.
The sofa bed was spacious and comfortable, all amenities were available in the kitchen and the views from the deck of Barcelona were fabulous. We had our breakfasts and some meals at night overlooking the sights of Barcelona from the deck.
There are plenty of shops close by, you can walk into main part of town in 10 minutes, a supermarket 3 minutes away and Fontana metro 5 minutes.
