It is good location. One stop by Catalunya, but really closed. You can go there 5~10 minutes by walk, and other famous place is also closed.
The apartment is very clean and interior is nice. It provides everything for stay, even something like book, cards, crayon for kids. Actually my daughter loved them.
It is easy and fast to communicate with the host(Oriol) by whatsapp.
If I were to point out anything at all, instruction how to use washing machine. But he let me know it kindly on whatsapp.
