If you're looking for a clean, nicely renovated, very central apartment for 1-4 people this is a very recommendable apartment. Don't expect fancy design but it's clean, quiet, very comfortable beds and a good kitchen. There's plenty of local life around the corner, including great bars/restaurants and unexpected little shops. You're only 100 meters from Ramblas but if you stay on the right side life is local.
If you're only 1-2 persons I recommend apartment 1B in the same building and same floor). It has a more spacious living and a nice balcony on the garden side (Wifi reception was weak but probably something that can be fixed). We were able to have a late checkout by moving our stuff to this apartment.
