The 3 of us had a lovely stay at Andei's apartment. It's a modern, well-stocked and professionally managed place. We were met by Mario as agreed, who showed us everything in the apartment, was very polite and offered further help. The building is really nice and the surrounding area was enjoyable - close to transport links, close to Sagrada Familia but still with a local feel to it. The apartment is pretty small (bathroom's tiny!) but for us it wasn't an issue. All in all, I'd recommend the apartment to 2 people or a couple coming to visit Barcelona.
