This is a great apartment. It's large and spacious. The kitchen is well-equipped and I loved cooking in it. Large refrigerator.
Marta is a lovely host too. She was very receptive to our needs. I definitely recommend staying here.
The place is very accessible for public transit. Lots of great food joints. Apparently Barcelona's best Gelato place is in the same building at the corner. Multiple restaurants that command 1+ hour long waits.
Only thing to consider is Barcelona can get really hot in the summer. So be sure to use the fans a lot.
