I couldn't reccomend Montse's place more, she was a wonderful host and gave us a very warm welcome when we arrived as well as some local tips. She even accommodated our early arrival time. We were very comfortable in the apartment and Montse does a great job explaining how everything works and makes sure you are clear on getting in and out of the apartment and using the available amenities. There is a metro station very close to the apartment but we ended up just walking everywhere as the apartment is very centrally located to attractions and food options. You can't go wrong booking with Montse! :)
