Overall, we were very happy with Fernando's apartment! We found it very clean and when we arrived our host had already provided several foods and drinks for us, which was very kind and highly appreciated. The apartment is very cosy and located in a quiet neighbourhood, which is, however, very easily accesible from the airport. One can find several stores as well as restaurants near by. It is also very close to the metro station "Urgell" as well as several bus stops. (We highly recommend using the metro to cover longer distances in the city, it's very cheap and very comfortable!)
We would highly recommend Fernando's apartment to small groups visiting Barcelona!
Thank you very much, Fernando!
