If want to feel a bit like a local during your stay, this is the place for you. Beautiful apartment with everything you need (kitchen, washing machine, fast wifi, small patio to sip your coffee in the morning). It is IMPECCABLY clean. Most importantly, it is conveniently located to La Sagrada Familia and it's about a 37 second walk to the metro, which means it's close to everything Barcelona has to offer. If you plan on visiting, research the Metro. It's the EASIEST and CHEAPEST way to get around Barcelona (if you use google maps with transit enabled on your phone, it will tell you step by step, it couldn't be easier The cheapest/best option is the T-casual 10 pass).
THANK YOU to Rafecas & Miguel. The apartment was exactly what I was looking for.
