Francesca was amazingly nice and a great host! We didn't get to meet her very often, but could reach for her assistance anytime. She answered immediately and was very helpful. The apt is great and perfect for an extremely central stay in Barcelona. It can be a bit noisy at night, but I guess it depends what time your stay is - our was during the city festival 'la merce', which was fun and loud ;-)
To sum it up: we definitely recommend staying at Francesca's.
Thank you for a great time in a great city!
