To all the fellow parents traveling with a young child: this apartment was just perfect for us. Ernesto provided a crib and a high chair without charging anything extra. You can leave the stroller downstairs, because it's nearly impossible to climb those stairs with a stroller. The kitchen is perfect for preparing a a meal, which was essential for us, because in Spain people don't eat lunch at noon, like our baby :) Bus stop to Gulliver or the aquarium is a few steps away!
Communication with the hosts was as easy as breathing, and the check in was flexible.
For us the narrow staircase just added to the charm, it doesn't happen every day that you sleep in a more than 200 years old building!!
