Stayed 4 nights in mid-February with my wife and two preschoolers. Friendliest and most helpful staff anyone could ask for, a washing machine/dryer in the room, spacious bedroom with a moving wall that separates the living room (kids slept on large sofa bed). Neighborhood is fantastic with a Deutsches Bank about 1/2 mile away, a Leonidas chocolate shop, nice bakeries, a candy store, a place for great jamon called Don Ulpiano around the corner. The closest metro is Hospital Clinic, which is about an 8 minute walk away. As others stated it can be quite noisy in rooms facing the street (I didn't put it together until after I arrived that there's a hospital right up the road, and you can hear ambulance sirens at all hours). So the windows in the room could use some better soundproofing. Rooms have a coffee machine (pods on sale for 4,50 euro a bag downstairs), a dishwasher. Lots of kitchen utensils, a small stove with 2 burners, no oven, a microwave, large fridge. An elevator is available. Building is secured by a locked door where you need a code. Strong wi-fi included. Not really negatives, but some things that could be improved upon: safe was available, but it wasn't secured to an immovable object, meaning I (or anybody) could pick up the safe and carry it anywhere. The bed was fine for sleeping, but since it is two twins pushed together, a bit difficult for extracirricular activities. The place is great, but 140 euro a night is a bit steep, but Barcelona is quite a bit more expensive than cities in Germany.
