Constance is a great host. I checked in really late at 11:30.and she was awake and constantly guiding me from the airport. Her place is a 3 minute walk from Las ramblas but it is uncanny how quiet her neighbourhood is. If you want to stay close to the heart of Barcelona, then this is definitely a place to be. The only thing you need to keep in mind if you are a big person is, you might have some trouble using the restroom as it is a little cramped. But Constance is upcoming and forward about it from the beginning :) will definitely come back again
