The location was perfect, with a metro stop 2 blocks away. There is a bakery across the street and a small market downstairs that had all the basics. There are air conditioning units in the living room and bedrooms, which are perfect when you want to escape the heat or humidity from outside.
The unit is located on the 4th (or is it actually 6th?) floor (ground, unit zero, 1, 2, 3, 4), and I will admit the first 2 days I had to take breaks on every other landing because I was so out of shape. But by the end of our stay, the stairs were no problem.
Josep was friendly, responsive, and helpful, answering all my questions quickly.
I would stay here again the next time I am in Barcelona!
