Stayed as part of a work trip, and was perfect. We arrived late, but were able to self checkin through a key box 30 min walk / 5 min drive from the apartment.
the apartment itself was spacious, and ideal for what we needed.
it's a 5 min walk away from the sagrada familia, and its metro, and a 15 min walk to the design museum where our event was.
highly recommended, and if possible, will return again.
