We loved the apartment. An easy taxi ride from the airport and clear instructions on how to enter the apartment. The location we enjoyed. It is opposite a small park which also has a few simple cafes to enjoy a drink and tapas. It's more for locals, but 10 mins away are the more touristy streets and metro stations and Sagrada Familia.
The beds were comfy and I was pleasantly surprised at how quiet it was given it's on a main street. Plus the blackout curtains worked very well.
The apartment is clean and simple and the washing machine was useful.
I guess if I had to find a negative it would just be that the TV was Spanish only but to be honest I am glad we couldn't watch it lol. And the master bedroom shower struggled to get hot but the other one was always hot.
Highly recommend.
