Trikua' s home was perfect. It was literally down the block from Sagrada Familia. Access to public transit or taxi's was plentiful. The apartment was very clean and wholesome.
Just an FYI for the stairs. We were sort of taken away because it's the second highest apartment in the building and the stairs are pretty long but it is not a complain at all when you are looking at the view on the balcony. The wifi did not work for us as we thought. However I will say that our American iPhones had trouble in every part of Spain we were in so I would not place that on the place at all.
Trikua was very active in communication and I 10/10 recommend and WILL be coming back when I visit Barcelona again.
