Amazing place, 5 min walk to the impressive Sagrada Familia, supermarket a block away and mini market just in front the apt. Subway station Sagrada Familia and L2/L5 trains will take you to Las Ramblas and Pl. Catalunya
in about 15mins, also there’s a City Tour Bus stop right at the Basilica. no Uber in BCN, just Cabify (6-8€ to Pl. Catalunya) and Taxis will be 1-2€ more expensive. Airport is about 30mins away (30-40€)so consider this. Space is enough for a mid size group 4-6, communication was constant and efficient, they are worried about every single detail in your stay which we appreciated also Welcome package is an amazing touch. I recommend the italian and the tapas restaurants just at the corner in case you want to have some food prior or after your visit to the Basilica.
