It is a Prime location to do anything.
We only were in Barcelona for 1.5 days but because of the location, we were able to do a lot of things in just one day!
The apartment is good size for 2 but for the price, this apartment is pretty good!
You can hear through the walls and outside but if you are from somewhere like NY, then its not a huge problem. You will get what you paid for!
They also provide guide map and metro information. If you are going to Barcelona for the first time, this is awesome locations to pick!
30 mins from the airport with Taxi. (DO use the local taxi app "MYTAXI")
