Clean, spacious and perfectly located to explore Barcelona by foot or by metro. The listing is accurate and the space was quiet, comfortable and even nicer than expected -- having laundry was a HUGE bonus. Another great perk: the water pressure and hot water. We were only staying for a few days, but the unit would have been comfortable for a much longer stay - great amenities (though we never cooked in the kitchen because there were so many good restaurants near by). There's a sort of grocery/convenient store just around the corner too.
The unit is, as other reviews mention, at ground level and the door is through a sort of 'mechanical room' area of the building, but we never felt unsafe. The mechanical area is accessible to anyone, though no one was ever in it, but the unit is private and locks up nicely. And the broken window 'as if someone was trying to break in' that another review mentions is very clearly due to the glass window on the door hitting the knob on another door and breaking a little. We felt cozy and safe and slept soundly.
Aside from a small check-in hiccup, which was fine because we were relatively flexible in our arrival/travel, everything was great.
A few restaurants we liked: Cuidad Condal, Brunch & Cake, Sensi
