Our stay was pretty nice in the center of Barcelona. It was about a 12-15 min walk to La Ramblas so the location was good. Apartment was big, spacious and well equipped. Kind of perfect for just about 4 people with privacy since the living room would turn into a small private space too.
However the Sofa cum bed was extremely uncomfortable to sit on while open and just about okay to sleep. the sides would even hurt while getting up from the bed. That bit was not great.
However, overall it was a good stay but priced on the higher side too.
