The flat was great, perfect for the two of us on a break to Barcelona. It was as described, and it seemed a bit bigger than in the pictures. Although everything was great about this apartment, the best feature was definitely the location. It was 1min walk away from the central square of the Gracia area and just perfect for exploring the city (although we ended up spending most of the time in Gracia!)
Make sure you're happy hearing your partner/friend in the bathroom and seeing their outline in the shower as the toilet has a curtain to separate and the shower has a glass block wall (I guess this would only be an issue sharing with a friend!)
Couldn't fault the flat and would definitely stay here again, loved the flat and the area was the best bit about Barcelona.
