I only stayed one night and didn't get to meet Claudia, but her mother let me in and was very helpful and welcoming.
The room is great for the price - quiet, safe and secure, and a comfortable bed. A fan was provided which helped with the recent heat, and was a nice touch.
It's a good location, easy to reach anywhere via public transport.
I'll be visiting Barcelona for longer at some stage and would definitely stay here again.
