We stayed for almost a week in Arne's apartment. He and his colleague are super good hosts and even gave us a mini tour of the apartment and the area at the time of check-in.
The apartment is extremely well located to explore Barcelona. It is literally 2 min from the nearest metro station and also from Diagonal. Major supermarkets and restaurants are in the same block as the apartment.
Arne, being an excellent host, provided all things of utility including Nespresso coffee machine in this nice and airy apartment.
I would like to come back again to Barcelona and stay at the same place!
Thanks Arne!
