Natalia’s place is wonderful and has what you need. The location is fabulous, but a bit close to the tourist hot spots. The sun lands on the terrace in the late morning, which is perfect, as there’s no reason to wake up early in Barcelona. We bought our own larger espresso pot in the store next to the entrance and brought it home. Natalia provides a French press and standard sized espresso pot, which is fine for most people.
Go north for a more local experience. We especially loved the Garcia neighborhood near the Fontana station. We loved the Bon Area store for basic foods. Even the cheapest red wine was good.
Only buy the single zone train ticket. Avoid restaurants with pictures of the food outside. We generally tried to avoid any area with such places.
Career del Parlament is a fun little street with excellent restaurants.
If you want great beer, go to Brew Wild BCN
