We had a few days to spend in Barcelona in August, during the heat.. what a wonderful relief this apartment was, with air conditioning and a beautiful roof terrace to enjoy the breeze when it picked up in the evening. You cannot fault this place at all.
Be aware, there are 5 flights of steep, narrow stairs. Not good for large luggage or easily-tired persons. If you're not afraid of stairs you'll be up quickly to enjoy the view across the large boulevard of Gran de Gracia and the rooftops, along with the well-appointed kitchen and facilities. Very comfortable beds too, and fibre internet! A winner for us, wish we could have stayed longer.
