We only stayed with Montserrat for one night but she made sure to attend to our needs, even feeding us a delicious traditional breakfast in the morning. She is a lovely, gracious host. I wish I spoke more Spanish so I could have communicated better with her!
The only downside was the room was very small for two travelers with carry-on sized suitcases and the building's elevator was a bit finicky. Not a deal-breaker for a one-night stay but keep that in mind for travelers who are looking to unpack.
