Mariajesus, Fran and Dubraska are very kind and available, we couldn't find better hosts.
The apartment is wonderful and well located: we easily reached the city center, the Oceanogràfic, the Ciudad de las artes y ciencias, the Hemisfèric and so on.
What we found really useful is the safety box placed outside the building where they can put the house keys in the event of a late check in.
We do really recommend Mariajesus, Fran and Dubraska's apartment.
