Absolutely the best! It cannot be overstated how perfect the location of Elisabet's apartment is. Virtually everything is within walking distance (with perhaps the exception of maybe Park Guell). The only time we took a cab from the apartment was to go back to the airport at the end of our stay.
Elisabet was the perfect host, communicating with us regularly throughout the day and accommodating us even as our flight's arrival was delayed by nearly 6 hours.
As for the apartment itself, we can't recommend it enough. It is worth the stay for the terraces alone, which are great morning/nighttime hangouts to take in the views of the city with a drink.
Thank you Elisabet! We can't wait to come back!
