Great location, we went everywhere by foot. If you'd like to go further, metro and bus stops are located very close.
Noemi was a great host, she told us everything there is to know about Barcelona. There were no problems with check-in and check-out.
The room is tiny, but sufficient to sleep in. There is one small window, but you can't see the sky and the room is dark all the time. There are no locks, but you can trust the host. The kitchen is shared with the host.
Our one major complaint is that the room, the kitchen and the bathroom weren't as clean as we'd like.
The Wi-Fi has weak reception, but if you have free roaming, it's not an issue.
If your priority is location and you turn a blind eye towards cleanliness of this place, we highly recommend it.
