The apartment is well equipped with everything you need and the interieur looks ok. The location is also good; near the metro and close to the Montjuic. The numerical lock at the entrance is very practical and makes sense in several people stay there. That way they don't have to around the key. Also, the staff who supported our checkin was super friendly.
BUT:
Please also be aware of thieves even just in front of the entrance of the apartment. Everyone knows that you really have to be aware of pick pockers in Barcelona. In this regard it is not well thought through that there is a huge lighted window which says touristic apartments. That is probably why we were robbed just when entering the apartment building. This should definitely reconsidered in my opinion.
