Me, my husband and my son stayed in August at Fiona and Phil apartment with another couple with their baby. The flat is fully equipped, very well located and near to metros and buses. Anyway the apartment is silent and quiet. The apartment also has an incredible view to Barcelona's Tibidabo mountain and a pleasant balcony. We stayed very well with the kids as the flat is sunny (but not too hot during summer!) and roomy.
We have to say that Phil and Fiona were very helpful and nice, ready to listen to our needs. Very nice persons and hosts.
We really recommend to other Airbnb guest Phil and Fiona's flat!
