The apartment is beautiful, it looks a lot better in real life than in the pictures. There were 4 of us and we each had our own bedrooms 3 king size bedrooms and 1 single bed. Perfect for up to around 8 people, 9 if you can fit one on the couch.
You also get a pretty new dishwasher and separate dryer which is in a separate room in the kitchen so you can have it on and not have the sound affect you in your bedroom, a small thing but important.
Lastly the location is the best part in my opinion, we rented bicycles and were about 10 minutes from Gaudis cathedral and about 15 minutes from the beach. Love it.
