I stayed at this place for 2 weeks in November with my wife and 2 y.o child. We really liked the apartment and its location in BCN. The apartment is spacious and comfortable, there is also a large kitchen with everything you need, there is a washing machine and a dryer, two bathrooms. Cozy balcony. The house has an elevator (which was important for us).
The beach of Nova Icària is literally in 5 minutes walk, but at the same time the area is not vibrant and touristy at all (compared to Barceloneta beach), it is rather calm. Metro station "Ciutadella - vila olimpica" is in 2 bus stops or just 12 minutes walking. Supermarket is also very close.
Also Silvia and her daughter were very responsive, helped us with useful information and instructions when our child got sick, nice persons!

Overall we enjoyed staying in this place, I can certainly recommend it.
