The location of the house is so perfect that you can go to most places to be seen by walking. To reach some places you need to use metro and Liceu Station in La Ramblas is right next to the house. You can find every kinds of need around the house.
And the house is enough big for 6 people. We stayed 6 days and didn't have any accomadition problems.
Although the street is noisy, the apartment is very quiet.
Lastly, Rosa is so friendly that she helped us before coming and during staying about the house, transportation and city.
We highly advise to stay in this house.
