We booked the apartment for a month, and enjoyed our stay very much. It was very well equipped and everything was new, clean, and comfortable. The rooms were all a good size, and nicely furnished. There were some basic kitchen supplies, such as oil, tea, coffee, and an assortment of seasonings. There is tons of storage everywhere. We loved the location: a short walk to the beaches, close access to the metro, and just a couple of blocks from the Rambla Poble Nou, where there are lots of grocery stores, produce markets, bakeries, bars, restaurants, and interesting shops. Having a washing machine was a bonus!
There are a lots of stairs, so it's not a place for anyone with any kind of physical issues. The bathroom has no heat source, so it was very cold for showers in the morning, especially the floors. The ceiling has not been finished in that room.
All in all however, it was great and we would happily stay here again.
