We are a party of 8 and this condo is perfect for us. It has 5 bedrooms and 4 bathrooms and one 1/2 bath, so plenty of space and very comfortable. The balconies are spacious and have great view.
Pluses: near the beach, walking distance to nice beach, near a nice mall (Diagonal Mar shopping center), many good eating places nearby (El Corner Taulat has great tapas and paella), close to bus stops, metro not too far. A very positive point is that it's not in the center of Barcelona, so at night there is no street noise.
Minuses: not at walking distance from the center of Barcelona, so metro and bus are needed. But as mentioned above, the advantage is no loud street noise at night. We all slept well.
We had a few problems with toilet not working and the dryer stopped working near the end of our stay. This is minor but prevented us from giving a 5-star rating.
Overall, we are still pleased with our stay.
