Fantastic apartment great for hosting 4 adults and 5-6 kids - 2 families essentially; we were 2 families and our kids ages 5 through 10 all had a great time
The outdoor balcony in the heart of Barcelona is great
Location minutes away from taxis, great cafes, shopping and bars etc
Extremely responsive hosts too
Only minor constructive feedback would be a better television channel network- we were there during the FIFA World Cup and had to step out to a bar nearby to see evening games at 9 pm and beyond
