The 4 of us stayed in Barcelona for 5 days in the flat that we highly recomend:
1. its 5 min from plaza espania meaning metro and bus also to the airport
2. its 5 min from a mall with big supermarket small shops resturants and what ever you need
3. the flat is by far one of the best since it has everything! salt, sugar, oil, tea, soap, dishwasher ect
4. the place is claen and well decorated and comfortable with great wifi and the little balcony is fun
5. the hosts are evalable at all time and realy healpful with everything you need
will love to come back once in Barcelona again
