Wow - what an amazing apartment! Very well thought out (for example USB charging sockets) and a beautiful design. Everything you could possibly need is in the apartment. We had a small issue checking in but it was resolved quickly by the helpful staff on the phone line who are available 24/7.
The apartment was in a great location with easy access to public transport. You'll find plenty of amenities in the local area and the roof top overlooking Barcelona was a real highlight of our trip. If you're traveling to Barcelona, I highly recomend you stay here.
