Excellent location near everything, including three supermarkets and a market within a block and just four blocks to Passieg de Gracia and La Pedrera. The apartment is well appointed and has almost everything one would need for a few days or a few weeks. Lots and lots of fresh towels and pillows, clean and comfortable beds, firm mattresses.
During our stay there were only a couple of other apartments occupied in the building so it was relatively quiet except noise from the apartment above, nothing bad just living noises, furniture moving baby crying, water running. I would imagine if the building was full it could be noisy.
