Great apartment within walking distance to Sagrada familia. The apartment is clean and has everything a family would need for their stay. Loved that fact that there is a fruit/vegetable store right in front of the building with fresh produce. Went and picked up stuff from there pretty much every day. It also has a washer/drier which is convenient and allows you to carry less luggage. Metro is close by and we took it to multiple places.
One thing to consider is if road noise bothers you in the night. There is road noise that you can hear in the master bedroom. It did bother us, so we slept in one of the other bedrooms which was a bit smaller.
