The ultimate in luxury, space, service and also in a great location to explore Barcelona.
The top floor apartment and it's terrace has to be seen to believe it. it's phenomenal!
comfort, luxury, space, tasteful decoration... absolutely great!
Practical things: A taxi from/to the airport including tip is <€45. Everything else is walkable, or then there's a metro station at pass. de gracia (~5 min on foot)
There was daily housekeeping and reception/concierge service from 9AM to 6PM or later, so you are both safe and well looked after if you need tips or help.
Overall a great experience, which is easily comparable to the Mandarin Oriental. - Just with far more space.
