We had wonderfull time (5 days) in that apartment. We felt like at home. It was good decision to choose that one.

Pros:
- 2x big tarrace, both private, the upper one with great view, you can watch sagrada familia and drink cava ;) there
- big
- great location, a lot of city attraction are reachable by foot
- quiet, it is in a city centre but you can sleep well at the night !
- new and clean
- stylishly designed
- comfotable and well eqipped kitchen, big shower
- fast and stable wifi
- elevator to the apartment floor
- sunny
- free bottle of cava and wine :D, coffe and basic stuff for breakfast

Cons:
- wifi password is 25 letters long ;)

Strictly recommended.
