Everything was wonderful during my stay, and I highly recommend this beautiful apartment!
It has a fantastic location, is situated in a gorgeous building, has access to a great (shared) swimming pool upstairs, the interior is very modern and really high-end (as a small anecdote, I asked them about more details of the mattress, because I haven't slept on such a great mattress in years - now I want to buy one like this for my home!). They took great care of me and were extremely helpful from check-in and the first day all the way to my last day and check-out.
Thank you very much for this wonderful stay, and I'm very much looking forward to returning in my next Barcelona stay!!
