Great location 5-minute walk from Sagrada Familia and metro. Opposite apartment is a small supermarket for essentials milk, tea etc Apartment was clean, bedrooms are compact but comfortable, great shower. The area itself was quiet the only noise was from people coming and going from other apartments.
We used Aerobus to get from airport to Catalunya Square and walked up to apartment, we had a late flight so used secure locker to put our bags near Catalunya Square. We will be back to visit Barcelona.
