We had a few issues but overall loved the apartment. We took the aerobus from the airport to Placa Catalunya for 10 euro round trip where it was only a 4 block walk. The apartment was spacious for 2 and well equipped. There was a bottle of vino and espresso waiting. The 5th floor patio was amazing and had a breeze even on hottest days. La Rambla is only one door down with a large array of outdoor food and drink. The metro is one block over on Ps Gracia.
Our issues were with paying extra city tax and sending passport copies which we did not see in listing and then figuring out how to keep the air conditioner with motion sensor running during hot nights. Service guy came after a day and was very friendly. He taped paper to sensor and gave us fan. Once AC ran all night we were perfect.
