The pictures really do not do the views justice, I was blown away by the awesome views of the Sagrada Familia. The place also has two small balconies on which you can stand and take great pics. For the value, the place is really good. If you need 4 actual beds, the fourth bedroom is made using a pocket door so keep that in mind and its not very big.
Location cant be beat. Great access to the blue line metro which is maybe 25 steps from the front door. There is a small elevator to get up to the 4th floor which is helpful.
As has been stated many times here and its important to note, the bathroom is quite small with the shower being comically small. I had no issues in the tight space, but wider travelers will be quite bothered.
Would highly recommend for a trip to Barcelona.
